Nice info! I never would have considered the siphon issue with a power outage; super important reminder!
Happy it was useful 👍
Is it like a check valve?
Stops water from backing up?
Thanks you so much for the knowledge and help me getting my pond crystal clear. That Bog Filter is amazing. Thank you for what you do for all of us. Aloha! Blessings to you, and be safe. Vern
Thanks so much 😊👍
What a lovely thank you gift!!
You’re so deserving! I have learned a lot! You’re so welcome! ❤️🙏🏻✝️
You’ve made my day! 😊
Vern… everything about this comment reminded me of my grandfather down to you’re name. Thanks😌
Absolutely gorgeous Pond.
I agree with you. It does the same thing as a Wetland Filter. 👍😊❤️
Wetland filtration best explanation out there. Building my pond as we speak. Thank you
An extremely helpful video, especially about the hole at the top to prevent a siphon.
Diagrammatic representation is excellent for understanding 👏 👌
Hey OZ ponds. What a God send to find your library of pond and filter approaches. I have been googling things like bio filter and plant pond filter. Very happy to find your labors!
I am in Thailand so hope to show the villagers how to have a clean pond.
I’m happy you found me too! Great name by the way 😉
Hey mate, your knowledge and instructions are second to none… well done.
Glad it helped 👍
Hi Kev! Thank you so much for teaching me all about what I need to do to get my pond crystal clear. I built a bog filter according to your ideas...and my pond cleared up in 5 days! I am a believer and wanted to thank you so much for all your info. I am grateful =D
That’s wonderful to hear 👍
thankyou so much for all ur info i installed a bog onto my pond and lo and behold no more single cell algae and water is crystal clear!!!!
Works every time 👍
I'm just at the final stages of building my pond. I wish I had seen your channel BEFORE now!
I’m sure you’ve done a great job 👍
Your pond is absolutely beautiful, my dream pond! Thank you for the informative video.
You’re welcome Lillie and thanks.
super detailed and educational, as well as some beautiful ponds u have there. 10/10
Thank you
Thanks for a very informative video. I have a small patio pond (132 gals) with a bio-filter and 2 barrel veggie filters. As my fish grew I needed to increase my filtration. Last summer I added an under gravel series of PVC pipe for more bacteria to grow. I pull the water down through the gravel that covers the PVC pipes then back up into my veggie filters. After watching your video I am going to change to a 55 gallon barrel (or 2) for my veggies filters next year. I lost an old koi from a power outage and my pond syphoned dry. I learned a sad lesson. I now have check valves on all my water lines. Thanks again. Love your ponds!
Sorry about your fish.
I have to say this is the most informative and relaxing channel I've found on keeping eco in ponds here on youtube. I seriously love learning about how to do all this. I am making a pond next month. So excited to try some of these methods.
Thank you so much. I subbed yesterday. God bless you brother xxoo
Thanks for the kind words. Good luck with your build. Everyone needs a pond in their life 👍
Thanks kev
I am planning a large swimming pond (with fish) project that will utilize rain water from my roof with DIY bog filters along the pathway and solar powered pumps to corculate the accumulated water back up through the bog on sunny days.. its a big project but excited to see it all come together..thanks again for your knowledge sharing.. i am looking at many designes and plans before making my own system..
Always a good idea to look at multiple systems and decide what will be best for you 👍
Thank you for this! My pond is much better now!🐠
Awesome 👍
Hi Kev great timing just about to start on my bog filter in the next week or so just buying all the bits to get started now winter is nearly over 👍
Awesome Sam. Can’t wait to hear how it all turns out. You’ve been an awesome supporter of the channel 👍
@@Ozponds thanks Kev will keep you updated and send some pictures when I’m up and running 👍
Thanks for everything you gave us in this video and your DIY ideas. I was happy to see a fellow "use what you've got" type mentality among all of the "how to pond " sites that use the brand name/high $ products. It was bad enough buying the liners.
As far as "follow these steps and you'll have crystal clear water every time" - I have to say Not Every Time. I've been doing ponds for several years and currently been working on my bog filter for two years. I haven't had even partly clear water yet. I have one pond flowing into another (approx 1200 gals and 1500 gals respectively) - the first has been reduced to half bog filter and half left to flow into the second pond. Lots of rock and gravel in the bog but only a 1200 gph pump for the 600 gals of bog. I live in the desert, full sun, and probably not enough plants in the bog right now. I'm hoping that as the plants develop and a second pump dedicated to the bog flow, the filter will be able to clean up the water. I have also added bio-media to the inflow barrel of the bog. I have a solids filter barrel and will probably add another barrel for a moving bio-media tank. I love the challenge of building ponds with generic products and seeing good results - I'm sure I will get back to a successful, clear, and healthy pond before the summer season ends. Thanks again for your time making these videos.
Is the water being pumped into the base of the bog? I’ve never had a problem with an upflow system.
@@Ozponds Yes, it is a reverse flow from the usual. The water is flowing down the snorkel, into the water reserviour under the gravel, up through the gravel and back to the ponds.It has been set up that way since spring with added bacteria but very few plants. I'm thinking I need to get more plants sending their roots into the graduated gravel.
I have a second theory: I may need to get a better seal at the bottom of the down flow barrel/snorkel and out to the under gravel reserviour to make sure the water is actually being forced up through the gravel and not just coming back up around the barrel. Thanks for your interest. I will get back to you if I am successfully producing clear water.
thank you so much for sharing your knowledge. Beautiful ponds . 🥰
I’m glad you find my rambling helpful 😊👍
Great video, informative and concise, thanks
Thank you Kevin. Your videos are a mine of information... I will keep viewing all your videos and taking notes. I am thinking about what we want to build and you are helping me realize what I am (& not) capable of doing ;o)
I’m so glad you find them helpful. 👍
Awesome sir
Great explanation not to fast but not slow either
The drawings help alot
Glad to hear 👍
Hi Kev great informative videos I modeled my bog after your sugestions and have beenpleased with the results
Great to hear Mark 👍
Thank you for your idea. I used your model and my pond went from green monster to crystal clear within 3 days.
Perfect 👍 spread the word.
Been wanting to make a swimming pond, so this video was God sent
Hope it turns out great 👍
so psyched to build one of these! I just finished building my main pond, and I'm glad I found your channel BEFORE finishing the rest. Now I can incorporate the filter into my pond pretty seamlessly rather than trying to shoehorn it in...
Awesome! Welcome aboard 👍
I'm just rebuilding my 2500 gallon pond that requires a total liner change. Incorporating a bog filter in a one piece liner into this one instead of the external bio-filter tub I used before. Going the 30%+ route because I love my fish. Won't have the large amount of goldfish I had before, just a few large koi.
@@mikejessmax hell yea, that sounds awesome! Haven't done anything with fish yet, waiting for all my plants to establish first so the ecosystem is ready, but I went way overkill on the pump and filter in preparation.
My issue is the pump in the pond can have the cylindical filter plugged in no time. I think I will build the filter and run the pump with no filter and hope I don't burn it out. Also I have an old pressure washer pump I may try to use this to pull water from the pond and pass it to the filer.
@@donvitokoski2846 build a little filter box to keep the pump in, finer filters at the bottom and more coarse ones at the top, leave space for the pump to breathe a bit, and you shouldn't have to worry about debris clogging the pump because it will always have some clean water around it. Just an idea, but it should work
Mega helpful video 🙏🏻
Thanks Bro. I will try it out this spring.
Have fun! 👍
I have already completed half the construction for a grey water cleaning system .
But this is very useful and still time to integrate.
My first outdoor filter was for grey water. One of the best decisions I ever made 👍
Thanks so much for your knowledge ❤
I hope it helps you create something that brings you lots of happiness 😊👍
Thank you. Much appreciated information
Glad you thought so 👍
I love your work. And how seemly is easy for you to show us the how's and why's. Cheers
Thanks 😊
Great video
Tyler Jordan Alex - Great Video to start your understanding of pond life.
Oh my Gosh, thank you thank you thank you! We are starting our swimming pond after years of wanting to. We let our small plaster pool go years ago with mesqito fish (basically a swamp) because chlorinated pools are not environmentally sound (as you know). I purchased the bad ass 30 ml. liner and felt last year and have been hand collecting rock. Though I know it can be done the bog filter has stalled my confidence even though I have latitude (books). Not any more though. I most definitely will be back and with pen and paper... and husband! 😂 🙏🙏🙏
Sorry about the typos. I/we will return for another look at your suggestions. It took a bit of time to find you. Question, this will be a swimming pond/no fish will the bog plants be ok with no poop?
Yes they will. They might struggle to start with but don’t worry, it’s the bacteria inside the bog that are most responsible for keeping your pond clean and healthy.
I have a 30k litre pond, fed up of green water and not able to see my fish. I decided to fill it in but one last shot post into a UK Facebook group before I filled it in. Due to the size of my pond, the members suggested a large bog filter. Your name and channel came up numerous times so here I am watching from the UK.
I no longer wish to fill in my pond! I’m going to design a bog filter thanks to your video.
Great channel bro, I’ll be sure to watch them all.
Wish me luck!
Good luck. I hope you finally get to enjoy the pond.
Did it work? If you did it, it probably did work. Good luck.
@@francus7227 yes it worked, 85/90% clarity within 6 weeks! A lot of work but well worth it, although a heron got one last night now he can see the fish.
can be used in akvariums too, false bottom and ex airlift that create a slow flow and anoxic conditions just give it time iron fertilizer help it to start work
Yes 👍
Alternately you can make a filter using a 55 gallon water barrel with pea gravel or lava rock and sand. This can also be hooked up to a rain gutter. Very cheap very effective.

Great idea on having the skimmer and bog within the EPDM pond liner to prevent leak potential. How do you rout the bog clean out at the bottom if the filter is within the liner and the valve is at the bottom?
Check out the large bog filter video or designing a bog filter video. There’s a cleanout port 👍
I think you have got it figured out. Totally love all your bog filter pond systems.
That’s great to hear Ken 👍🍻
Your idea for a bog filter is absolutely amazing! We’re planning on implementing a bog filter for our new duck pond, but after using the calculations you gave in the building tutorial vs in this video we’ve come to a bit of a problem.
Using the calculations in the other video we came to the conclusion a 1000l pump would be sufficient for a 250l pond, but after watching this video a 1500l pump would be necessary.
I’d love to hear your opinion on what would be the best course of action in this scenario!:)
Anywhere in between would be fine.
Love your videos. We dug a small pond last year - no fish - we are trying to attract dragonflies. We live in the northern hemisphere where it freezes in winter. How do you handle bog filter in winter? Turn off pump and drain it? I would love to bury a 55 gal barrel so it’s hidden but then can’t have a lower drain outlet. Been binge watching your big videos all night - my guess is you don’t have freezing winters down there?
No my winters are mild. I’ve had many people tell me they shut their bogs down for the winter no issue.
I put your video in my watch later file.....but I hit the like button already because I know I will fr👍👍👍🤭🤭😎🛐✝️🐣🍟🐧🌵
😂 nice 👍
dear kev wow awesome I was wondering how far down the inlet pipe should the hose from the pump go down the bog all the way or only some of the way ,?you have helped me so much cheers
I find it best if it goes to the base of the filter.
Start to put into place building a wild life pond in our front yard food forest and your videos pop back up with a mountain of information.
I might have a place for a bog filter, and wanted to try a "flood plane" as the upper pond. Be cool if a I can find a variable pump that can cycle between volume.
The pumps in my dream pond have variable flow settings.
@@Ozponds only issue is I can't find one that I can cycle up and down automatically.
The guys at aquapro gave the idea. Use two pumps, one on, one you can turn on. I can use an arduino to control the second pump.
Thanks!
You are wonderful. Thank you so much for your support 😊
thanks
Hi Kev :) Loving your channel mate. I definitely want to hear more about running a higher level pump through/over as a stream (mentioned at 5 min mark) and really hope you make a vid on that topic soon. That would mean it was the only filter/pump yes?
Putting in an 800, want to put one of the bog filters on and trying to work out the best way to do it. A 250 bog should make it a reasonably stable size for goldfish I'm hoping :)
I’m not sure I understand the question. I used a high flow filter as the start of my stream on the dream pond (there’s vids in that).
@@Ozponds sorry :) I'm talking about the moment at 5.23 where you are talking about using oversized pump in your bog in a barrel build. I notice in the dreampond inground bog build you solved the problem of keeping the water for the bog slower underneath a faster stream by using two pumps - one for the bog and one for the stream head. You've made reference to the same problem here, and said it was a topic for another day, and I'm sure hoping you did put it in one of these lovely talks. My question is, in that barrel build you mentioned, was the bog filter the only pump/filter or did you end up using 2 pumps like with the large build?
Ah I see why I’m a bit confused. The bog filter inside the stream is a seperate system to the dream pond, although the same style of filter. The dream pond has 2 dedicated bog filters and a stream with a high flow filter. I have talked about sending excess water over the surface of the bog if the pump has too much flow. I can’t remember the best videos but I would imagine I mention it in this one - What is the minimum flow rate for a bog filter?
ua-cam.com/video/n29ev7xEvy4/v-deo.html
In regards to the pond with the barrel bog, yes the bog is the only biological filtration and there is only one pump. The pump sits inside a diy skimmer I made using a bucket. There is a sponge over the top that provides a little mechanical (catching larger debris) filtration.
Hi Kev, can u explain in details how to stop siphoning our water from blog and getting it dried.? I did not understand it clearly where I need to put the hole? To have air rushing and stopping water from siphoning out..
I’m working on a new filter video at the moment. I’ll cover the siphon in more detail in that vid 👍
Hi Kev!
I’m really enjoying your videos. Is there a specific type of porous rock that you prefer?
Not really. The rocks you see are just cheap in my area.
Still totally enjoying your video's! This question pops up: would I need a bog filter if I make a 25 m long stream? It's going to be about 30-40 cm wide. about 20 m of the length is made of rock and pebbles and the pond (6000 ltr) too.
I would still add one. My very first pond was similar to what you describe. The water was perfect for 2 years then I started having issues.
Curious if when filling a bog filter if I can use batting in addition to lava rock or other rocks? Also what about using sand ? So I was thinking large rocks, stacked to smaller, then a layer of batting and maybe the sand on the very top. Wasn't sure if that would function correctly though. I'm asking because I already have these materials on hand. And if I can use sand does the type matter? Play sand or construction sand?
I never tried it that way. You would be experimenting.
I built a bog filter with the help of your idea. Loving it! But I have never ending mosquitos nesting in it. Any advise?
Make it either so that fish can live in it or completely cover the surface with pebble so there is no standing water.
@@Ozponds thank you. Pebbles cover would be a great idea
Very nice, thank you for sharing the knowledge! One question, would this kind of filter be suitable for a turtle pond? I know turtles are way messier than fish, so would this filter handle cleaning the water?
Yes 👍
Hi Kev,
when making your ponds and calculating water volume do you take into consideration the weight of the rocks?
No. I just work it out without.
Great video. If the bog is made just using pond liner (in sunken dirt) do we need a clean out valve? Thanks
The barrel acts as a clean out port.
Hi kev, wonderful video as always. I learned a lot from watching your video as well as reading from your website. Just one question stuck in my mind, do you need to have a separate solid filter when you have a bog filter in place? Especially when dealing with ponds with lots of fish in it.
You can design the bog so that it has plenty of space to capture solids. But if you prefer to seperate them before that is ok also 👍
@@Ozponds thank you so much for the fast and wonderful response.
Hi, so could I pump water from the intake bay together with water from the "sump" deep down of swim zone, into bog?
If you’d like too. I’m not sure what the “sump” is. I’m guessing it’s just a deeper part inside the pond. If that’s correct you will pump more muck into the bog so just be mindful that the bog would need more regular flushing.
Does it matter where in the pond the pump is? Could you place it in the opposite end of the waterfall.. like the way you would in an fish tank. Or does it become negligible after a few turn overs?
I’ve got vids on pump placement. Opposite side is good. You also want it protected so your maintenance is minimal.
Hey keV. Please how to direct the excess water flow? 5:20 ? Do you have a video about the topic? Thanks.
I think this might help Breather pipe for a bog filter
ua-cam.com/video/03Om94Fg5g4/v-deo.html
Great Job !! I bought a home with a pond(man made) It has no circulation and it is green on top can't see in water at all. I'm putting a waterfall in. Any suggestions to clear the green bacteria?
Many options. Watch a few more videos. Moving water through a good biological filter (like a bog) is the easiest way to improve overall health and appearance.
Hey kev- thank you so much for these videos! We're putting in a pond at the moment and the information is fantastic. We're very interested in this bog filter and I just want to ask you how big do I need to make it if my pond volume is about 30,000 gallons? I'm looking at that olive barrel thinking I'm going to need something WAY bigger than that! So my question is how much bigger? According to your formula, it wants to be 10% the volume of the pond itself, which in my case would dictate a 3,000 gallon bag. Is that possible in a contained environment? What kind of pump would I need to make that viable? Thanks
On my dream pond I added 2 bog filters. Both are built using liner so they can theoretically be made to any size required. I’ve never built a pond as big as yours. But you can build a bog in modules like the aquascape wetland system. You don’t need just one pump you could have multiple pumps feeding the bog. If I were building something that big I’d do lots of research, possibly hire a professional and then try to build the system using cheaper materials. But the fundamentals always stay the same: move water slowly through media (rock & pebble) colonised by bacteria, capture solids and have a way to easily remove the captured solids.
Omg can we talk about the moss tho! its so amazing. Do you have any tips to get your moss looking so amazing?
Just build it and it will come
Hello. Do you use pvc or vinyl to connect the pump to the bog input? thanks
I prefer flexible pvc, but I also use rigid.
I am looking to make one in Southern Wisconsin, how to I decide and find what plants to use?

Great Channel Kev !
Love your work !
Just a question tho ; if I was to design a bog or a barrel filter ; am I able to use Sandstone as oppose to bush rock ?
Possibly. It’s not a type of rock I’ve used. My only real worry would be if it’s so soft that it creates a lot of sediment that then clogs the filter. Otherwise I don’t see an issue.
Whatta legend u full replied ! That was my original thoughts . Bush Rock it is
One thing I've discovered that I hadn't thought about; A single outlet from the filter, back into the pond, makes a much nicer sound for several small outlets. The noise you get from several small outlets, makes me need to pee 🤣
😂 I have a pond like that. For me it’s more the volume of the pump. It’s that trickle noise that triggers me.
Just the episode I need! I commented before on the chlorine levels in my pond and it was due to me having cleaned the pond just before the test, hope that it condenses out properly. One question though, do you also have a smaller design?
Yes. If you check out the diy filter playlist you’ll find a few different designs I’ve used 👍
I have a well down into a Aquifer, I use NO chemicals but have a UV light system to kill bacteria.
Could i possibly use the aquarium filters using materials such as fiberglass hollow perbleles and carbon, in addition to this in order to accieve an even better effect?
And one more question.
How hygienic safe will be for a person to swimm in it?
Just in case.
I wouldnt like to use the usual pool chemicals if possible. Can i have the same result?
You can always enhance the filter 👍. Swimming is a personal choice.
Does it have to be above the pond? I need to make one for a pre-formed pond, and I was thinking of doing it more horizontally. I have to drill holes in the side of the liner, for bulkheads to pass through, so I don't want to be messing around with the pipe work too much. I was thinking of digging space for the bog next to the existing pond, down to a depth of maybe a foot. Then lining it with flexible liner, drilling a 30mm hole through the preform, a foot below the surface, and using a bulkhead to pass a PVC pipe through the rigid and flexible liners. Then at the other end of the bog, I'd make a sump to put the pump in, to pump the water back into the pond nearer the surface, back through the flexible and rigid liners.
That way, I can keep everything at ground level, and the only pipe work can be straight. But every other bog filter i see people making, seemes to be elevated above the pond. The only problem I see with the way I'm planning on doing it, is that the sump might run dry if the water doesn't move through the filter fast enough, but it makes more sense to me to have the pump in the cleanest possible water. Am I missing something?
Take a look at intake bay design. I’ve done a few. Sounds like that’s more what you are trying to create. The bog can even be inside the pond. All a bog is doing is moving water through rock, pebble and plants. The main reason we elevate it and keep it separate is that it’s easy to clean.
Hi Kev is it possible to use a layer of river sand in the bog filter to trap finer particles or will it compromise flow rate, I was thinking about layering sand between two courses of 9.5mm gravel
Ive never tried it so I can’t give you a definitive answer.
Great, looks good. Qik question, I have 4 bogs for my 4 connected water bodies. One of the bogs are basically 2m wide but 14m long, how would you evenly disperse the upward movement of water?
With a long, large drainage pipe through the centre. You can buy half pipes at Bunnings which are perfect 👍 and cheap!
@@Ozponds Hi, yes however that would have different amount of water coming out, getting less as it moves along. Perhaps I should T in like every 2m or so for even dispersion
I dunno. The pipe creates a void. It’s easier for the water to move through the empty space as opposed to the rock and gravel. So first it is dispersed through the pipe then moves up through the rock and gravel. But it’s your bog you can do it however you please. 👍 Bogs are super forgiving so even if things don’t go to plan great results are achieved. Best of luck 👍
I want to have a bog filter by using a liner instead of a container. Do you have a video that shows this please? Thanks, Mark
Yes you’ll find it in previous uploads. One I did in a stream and two on my dream pond. 👍
Hello, thanks to your videos I have built a simple bog filter though I have another problem with floating debris falling into the pond. Do you happen to have a design integrating both a bog filter and a skimmer using one submersible pump?
Yes. Many of the build vids talk about this and show it. If you look at the ecosystem pond on a budget, it should give you some ideas.
@@Ozponds cool, i guess i just needed to watch more of your videos 😅. love your videos and i REALLY appreciate your replying. thank you. you'll make my turtles really happy
Can the inlet for the water go directly into the bog container through the bottom side instead of over the top then down?
Not if you are going to add a breather pipe to prevent siphoning.
Do you have a resource or recommendation on an option other than AquaBlox and the Snorkel system by Aquascape?
Yes. Check out my dream pond playlist. I also have a vid on aquablox alternatives 👍
I have an idea to pump the water up to the little hill that surrounds the pond then create a bog filter channel/artificial stream which does a few switchbacks down the hill then goes back to the pond.
Any feedback on this idea? Its a pretty big pond so I figure I need max surface area.
Sounds like a good idea. 👍
Awesome video! Do you need a syphon break if you have your inlet drilled thru the bottom of the bog (basically at the same level as your clean out valve)?
Yes. But a normal air break won’t work. You’ll need to use a check valve.
@@Ozponds thank you
Gday Kev, love your videos- so informative! am embarking on my second creek/pond and this time going to put in a bog filter. Does it need to have continuous water flow or can I turn it off overnight? Was only planning on running 1 pump (I know you recommend a separate one) to circulate through the bog filter and also return the water to the head of the creek?
Better results running continuously.
@@Ozponds awesome, thank you. I thought as much to keep the biologicals from starving. Love ur work!
If you live in an area with clay dirt, and have 1 duck, would the dirt and mud clog the bog filter?
I think it would be quite problematic. I don’t really recommend bog filters for clay lined ponds.
Where can I buy the half drain pipe from? In US, cant seems to find anything similar online
I’m not sure. I’m in Australia. If you find it let people know 👍
Hi, I want to add a bog to my existing pond, yet I want to do it with out starting fresh on the old pond, meaning draining and getting a larger liner. Is there q way to add the new bog and overlapping the liners with out the water seeping or wicking between the two liners?
The end of the pond where I want to add the bog is slightly curved has the liner folded over itself (I hope this makes sense). I can not see how I could glue the new liner to the old with out the water wicking through the fold areas. Any help would be appreciated. Thank You
The easiest way to add a bog to an existing pond is by connecting the two with a stream or creek. If you have a slope this is easy. You can overlap the liner sort of like tiles on a roof. I usually like to allow 30cm (1 foot) if I’m not seaming the liner. But if you did need to seam the liner hopefully because the stream is narrow you could find a nice smooth piece (No folds) on the existing pond. I hope that makes sense.
@@Ozponds Yes it did. Thank You!!
Hello Kev. I just found your channel today and I am interested to your opinion.
I am looking to do a pond as a natural holding tank for the rain water and my grey water to be used for watering vegetables garden and the swimming pool...
Can a bog filter will work with the small amount of nutrients?
Does your system have a musquitos problème ?
I see the bog filter as a decorative features in my yard.
What do you think of this application?
Thank you for you help.
There’s usually rules around how long grey water can be stored for (at least there is where I live). I’ve built myself a grey water wetland/ bog but I certainly don’t swim in it, I’ve built other ponds for that. I don’t have issues with mosquitoes, I recently made a video on that.
Hello Kev, how many inches of rock/gravel do you recommend?
Depends on the bog size. I’ve used shallow bogs and deep bogs they all work.
Hi Kev, just wondering the size of those olive barrels you use. Approximately 80cm high and 200L?
That’s them. 👍
Interesting video
Still working on digging out garden fish pond.
I have 4 good sized raised beds approx 90’ long
The pond is between 80,000 and 100,000 litres depending on how deep I go. Thinking how can I use the center of the beds as the bog. Also incorporating the water flow in the overall watering of the gardens.
Sounds like you want a supersized aquaponic system.
@@Ozponds lol for sure will grow water spinach on a raft like structure. But mostly want to feed soil with the nutrient rich water. Talked to the guys building the pond we decided to build up two sides by extending the retaining block walls. But good timing seeing your video as I’m at that moment where decisions will have to be made.
Cheers
Sounds like a really fun build 👍
Slm. Hocam. Eğim betonu izalasyonculara anlatamıyorum. Bilgi ve birikiminizi insanlığa aktardığınız için müteşekkirim.

For some reason the translate button isn’t here, I can’t even copy and paste into a translator. So I’m really sorry but I don’t know what the comment or question is.
How do you calculate the amount of water through the regulator valve?. My waterfall is 30 inches wide 900 gph is what's needed for my bog according to your calculations.
Just connect a hose to it and fill a bucket. A few calculations and you’ll know exactly how much water is coming out 👍
Tks u, what kind of liner is good for (7wX8lX2d)m pond.
For me it’s always epdm rubber.
Hi from Spain, thanks a lot for all your videos. I have a cuestion, I´m gonna do a 5x4x1m pond with more or less 10.000L. I´m going to use your instructions for the bog filter. So i will need a 3,333L bog filter, i will use 4000L and i need a 24000L/H pump??? is not too much L/H? thanks and keep going with the videos they are great!!
For a 4000L bog I would buy a pump around 24,000L per hour, correct. Preferably variable speed.
@Ozponds thanks, I thought that was correct but also that perhaps it will be too much flow if I need a low flow... no?
This is just a simple way to do it. It can have less flow absolutely. Remember you’ve got the breather pipe, an intake bay, skimmer or some other kind of mechanical filtration. Then you’ve got head height, back pressure from the bog. The pump cage or sponge will become semi clogged overtime. This is how I do it but it’s not the only way. There’s lots of ways to filter water. I just find this simplified version works for the vast majority of situations. Hope that helps 👍
Hi. I have a pond with about 17,000 liters and no fish. How small can the bogfilter be? Thx for really great videos. :)
It sort of a how long is a piece of string question. Even without fish there can be things that add nutrient load. Runoff and leaf litter are probably the most common. Me personally I would always start with 10% but that’s not to say you wouldn’t achieve great results with 5%. You just really never know until you build it. Every pond is different.
What about for people in very cold climates? Won't all the plastic pipes freeze and crack?
I have no personal experience with that. My guess would be either drain the pipes before winter or bury everything below the frost line. But I’m just guessing, we get frosts where I live but nothing extreme, i run my ponds and filters year round.
Hi Kev, love all your vids! Learning so much!! Just wondering to choose the correct pump size, you say empty bog size x 6, my bog is 500L so i should be getting a 3000L pump?
Just wondering if you need to worry about distance away from the pond the bog sits? Mine is 2metres away do i need to size bigger for pump for distance away from pond or 3000L still enough? Thanks!
In that situation 3000L is fine 👍
@@Ozponds Thanks Kev. Should i worry that my pond is 4200 litres so it wont be turning over once in the hour? I'm adding a DIY waterfall filter to to combat this 😊
so the bog worked great but know i have parasites and its hard to kill them because of bog its hard to get them all any suggestions?????
But the bog should always be easy to clean and flush. It’s one of my design principles.
can I have the inflow of water connected in the bottom?
I don’t recommend it as it’s to hard to prevent siphoning. Check valves have tended to fail for me in the past. I think it’s due to the low back flow pressure.
What are alternatives for the everhard pipe for bigger bogs. There is nothing like that in the netherlands. Making my bog 1m by 1m and 1m deep. Suggestions are welcome. Thanks
Anything that will allow the water to disperse and accept the weight of the rock and pebbles.
@@Ozponds ok thanks
Hi Kev, i'm about to start digging my wildlife pond mostly for birds and a couple goldfish later on. I´m gonna do an undergravel grid attached to an Airlift. The Grid under gravel will have some sort of "diy aquablox" to protect the pipes from getting clogged. My idea is that the bottom of the pond is somewhat a BOG filter... Do you think that this type of idea might need a real bog filter? The pond will be about 2x3m (6mts2) and 1meter in the deepest area. Could i send you a drawing to explain it better so you get the whole picture.
I think it will absolutely work. After building the barrel pond with no pump from now on I’m going to create a false bottom in every pond! It makes perfect sense for the water to be able to move all through the substrate as this is what would happen in a natural environment. You can always contact me via the website. Just keep in mind I receive lots of emails, I do my best to reply promptly.
Is the pump placed in the pond?if so how do you not get electrocuted?
So far I’ve just been lucky. No submersible pumps are made to specific regulations so that they are safe. I think I talk more about it in this video. Submersible pond pumps|Installation|Maintenance|How they work

Hi Kev, totally agree with bogs and mine worked amazingly until I did my back 7 years ago and couldn't remove excess plants. The fish population increased from about 20 fish to over 300 that summer because the babies could hide in the mess. I have the bog about 3rd size of the pond and a bio filter too which also worked brilliantly until this summer. The fish got big, some over 30cms. I can't cull them, I don't know who I should murder, lots of them have names and some are over 17 years old. Any ideas? I thought about adding an intake bay but would need an excavator as we are all rock here. The free rock was great but digging next to an established pond scares me and there's not much room. I'd like another pond but that won't go down well with the other half. Water changes and splosht is keeping the water within parameters but not for much longer as the fish get bigger. They are eating all the plants now too.
If you are on Facebook or gumtree offer the fish for free. Or better yet fish and plants for people that will help you with a bit of maintenance.
