- I build a small no waterchange aquarium with plants and deep substrate for denitrification.
My goal is to slowly increase feeding and find out how much food I can add before nitrates increase.
How to build a no waterchange tank series:
• How to build a no wate...
What kind of light is needed to grow plants series:
• light for planted aqua...
I appreciate your creative and experimental approach to the hobby. You apply basic principles and show the way for hobbyists to set up and maintain balanced aquariums.
@@bonyylast7147 If it is fine enough to be mistaken for sand, yes, certainly.
One of the best channels on fish keeping! We're literally keeping the water here, and not the fish. Good water can then keep our fish 😉. Great job... love it! Thanks
I still believe that water changes are beneficial. What about other stuff that we might not be aware of, that's building up in our tanks? Doesn't mean that it's ok just because our fish are not dying. What about the life span of our fish, and their growth rate? Thats gonna take years for you to compare and figure out 😉. But... i'm definitely gonna add a deep sand-bed in my sumps. Thanks again ❤
Honestly, this is the most informative aquarium channel on youtube that presents actual evidence instead of just random speculation. You should have way more subscribers!
Good work. I have heard a lot of people try to disprove deep substrate planted aquariums online. This video is pretty conclusive proof in a working aquarium showing that it works.
It just works
@@Jaysaquarium Hello Jay! I love your experimental videos! Lately Father Fish is talking about using autumm leaves as well on the bottom of the tank in order to create a permaculture, wich deplets the amount of food you use daily to feed your tank. Any thoughts on this matter?
Kind regards from Portugal!
@@hugomouteira7015 hmm never heard of it. Not sure what the rationale for that would be.
@@Jaysaquarium me neither. On his videos he says that the leaves create a good environment for microbial and small animals proliferation
@@hugomouteira7015 It's a food web
Love the experimental approach you are taking in the hobby. It is surprising to see we share the same methods to avoid/minimise water changes in marine too (i.e carbon dosing, deep sand beds)
Thanks Jay, shocked how much food your aquarium could take. My 200 litre tank has glass condensation covers so I don't have to do top off's, deep substrate, planted with val, crypts, duckweed, no flow, no man made filters. Occasionally I do a water change of about 5% just to pretend it's raining, everything remains the same year after year 🍀
Sounds like a very nice tank
Love your stuff. I have 3 large and one small tank. No filters, water changes and no nitrates. Thanks for doing this.
didnt knew 0.1 grams is this much flakes :0 and all that without water change...i also made a deep substrate tank with soil and sand about 5-7 centimeters. Thanks Jay and father fish
I love your experiments. Always fascinating. Thanks for the hard work. Looking forward to more
I love your videos. I know you don’t post too often, but when you do it’s worth the wait. I have learned so much. Thank you!
Thank you for being patient :)
I remember when i got my first tank when i was a kid, i add beach sand, big coral stones, small filtration, couple of gold fish with tap water. No plants and other additional filtrations and only do water change maybe once or two every year. No light also. The fishes never died. Starting again this hobby, never realize how much complicated closed ecosystem is lol...but i manage. Thank for your videos bout "no wc vids" man...its really teach me so much.
This was my major question how much food my tank can handle. My fish are getting adult in almost a year due to lack of hi quality food. Because i feed them 3 times in a week. Now (thanks to some nice dude in the internet ) i know that well established tank can handle so much food than i am thinking. Thank you mister deep substrate :)
I appreciate your effort as it is very different from other videos on internet where people just talk about the open sourced information than actually testing of their own
Great experiment. I have a 5 gallon with deep substrate as well that has shrimp and ramshorn snails that is planted with a heavy duck weed on the top. I do not have to do water changes either. I also have a small sponge filter. Only one difference is I have an under gravel filter with "some" not much typical media in that space and I run the bubbler on the under gravel filter very very slowly. Just barely actually.
Sounds like a nice tank
Another amazing video. I like your approach, and the realness of it all. Thanks for putting the time in and sharing with us.
Finished your no waterchange vids a long time ago. Thanks for your great vids once again! Your vids are definitely worth waiting for
Just saying, you kind of made my newset tank go well, since I tried deep substrate after watching your vids and realising how essential it was
Good scientific method outside of a lab! Thanks for the data and analysis, it’s surprising the TDS side of things for me but then would need a tap water analysis to further explore that. But duckweed is magic for nitrate removal that’s for sure
Yes, I think a focus on the plants, which I suppose is in another video, is necessary as they are a critical piece to the nitrate being consumed. It'd be more telling without plants as to how well a deep substrate works. Would it even work just with that and a normal sponge filter?
I think Jay made a just deep substrate experiment on his channel before and it lasted 6 months @@weirdscience6820
Brilliant test :)
I've had great success just knowing the science you helped me understand :) my first tank is 3-4 months old now and I have had no problems at all ^-^ even managed to keep an otocinclus happy this whole time :)
Thank you for the work and effort you took and the time you put into it.
Extremely interesting experiment.
Amazing experiment, it shows the power of nature.
I wish you would do an experiment with no sponge filter too.
fantastic video, thank you for your experimentation!
Awesome experiments men. I love this kind of content
Very interesting. Thanks for sharing your findings!
Great experiment. Thanks for sharing
Cool one
You’re awesome. Keep it up.
This is truly fascinating. Thank you
Excellent content. Thank you for this.
Good job, Jay!
Like #80.
Great experiment and reporting. I would estimate that you plant biomass is at least 10X your fish biomass. The plants are doing the denitrification obviously and the stable nitrate levels has nothing to do with a deep sand bed. Your plants are eliminating any nitrate build-up, not any anaerobic layer in the substrate. The experiment does tell me you need quite a bit of plant biomass to have a stable system. I would not try it with larger fish like cichlids.
Well actually I measured the dryweight of plant trimmings in this tank, which suggested the plants accounted for about 70percent ofnthe denitrification. I did not include these results because i had some data missing due to mistakes i made during measurements.
That’s a fantastic video, well done!!
I use a similar system called a BCB basket in my sump filter made from cat litter and iron rich plant substrate. It does the same thing, ammonia to nitrite, nitrite direct to nitrogen gas.
Great information
Interesting
Can u make an experiment with bunch of goldfish to make it more challenging
Nice video
Very informative video with measured results. Yes 9mths is quite good. The duck weed are probably sucking up a fair bit of nitrates? The deep bed chemistry is very complex. You left out the nitrogen, lol. Protein to ammonia/ammonium to nitrite to nitrates back to nitrogen gas. Under low O2 levels another group of bacteria will use the oxygen in the NO3, thereby reducing the nitrates.That is probably in the anoxic zone. In the anerobic zone[total zero oxygen] Hydrogen sulphides are produced. I am not sure what happens in that zone as I don't have much knowledge. Can you shed some more light please?
Can you let this experiment go on to see if can touch the 2yr mark?
It is always great to see results from another angle.
I did not explain denitrification in this vid because I have a whole series that explains it in detail. Check the description. I also have longer experiments on my channel so I wont be continuing the experiment.
Great as usally.
That was very helpful, thank you, are those guppies the grown up original fry you put? And did the shrimp breed in this setting ?
Thanks, I've been following your method for the past 3 years and it works. I only did water change twice in my 5 gallon in all 3 years, due to moving reasons. Otherwise, tank is healthy with minimal maintenance. I'm going to set up my second tank for guppy using the same method. One question, do you see a change in fish/shrimp breeding behavior with such setup?
Awesome experiment! Thanks for sharing. Do you know if there would be a difference if you fed all live food (like BBS, daphnia, black worms) Or if you had something in there that only eats leaves and vegatables and you were never feeding processed fish food? Would that change things?
Would it change things? Probably yes. Would the tank still work? Probably yes.
I have some questions… Do lava rocks work as deep substrates do? Does the core of the lava rock has anoxic area? Thank you Jay! I’m learning so much from your videos!
I havn't tested lava rocks but i see no reason why they shouldnt work
Do you have any experiments around algae growth? It sometimes feels like algae outbreaks can be for very mysterious causes! I would be fascinated to know that if all things are equal, whether overfeeding, high phosphates, high iron, water column nutrients vs substrate nutrients or too much light (intensity vs length) is the greatest contributor to algae growth. There's a lot of different opinions on the causes of algae (when the cause isn't obvious).
Difficult experiment to do because so many species of algae.
Did you do any plant trimmings during this experiment? If not, are you planning on doing it? I wonder how much impact does this have on your experiment.
Trimming is essential. Trimming = removing nitrogen in plant tissue
Always enjoy your experiments! I have a question, does deep substrate have to be vertical? If you put those deep substrate bottles on their sides, maybe buried them in a shallow substrate, would they still do the job?
If i put them on their sides the substrate will spill out
Not if you bury them! Or cover the openings with mesh. Anyway, I'm more interested in the theory than the practicalities. Would a horizontal deep substrate work, or only vertical ones?
Would work regardless if you assume the substrate doesnt spill
Interesting!
Hey, can you please explain more on how TDS holds stable in no water change tanks ?
Precipitation, consumption by animals, consumption by plants means TDS reaches equilibrium at a xertain point
@@Jaysaquarium Thank you 😀
Thanks for the educational video. I want to do the same thing. Can you tell me what substrate did you use? Are they soil at the bottom and sand on top?
Yes. Dirt and sand
@@Jaysaquarium Is the dirt referring to the soil sold in aquarium shop?
No dirt as in stuff in your back yard. Or potting mix or anything that you can grow plants in.
@@Jaysaquarium Wonder if anyone ask this before. Why use dirt instead of the soil sold in aquarium shop?
Dirt cheap
Just curious if you were removing plants when they became over grown or not?
yes regular removal is essential
will PH, KH drop, if long time no water change ?
How safe is using artificial rock (made of concrete) for aquarium?
.
I read that cement releases calcium and other carbonates which raise ph of water and is harmful for fish. I saw a video in which they treat the cement to be fish safe by keeping it soaked with banana trunk.
.
Is there any other way of doing this?
It will raise water hardness. I cant comprehend the rationale for soaking banana trunk.
Hi Jay, can you tell the led used in DIY light making please.
Can you be more specific?
@@Jaysaquarium I was asking for the led used in this video. ua-cam.com/video/CS8BWJrZs30/v-deo.html
how deep does my substrate need to be for a 10 gallon tank? and also I heard that anoxic bacteria thrives and does better in neutrol to basic/alkaline water? will this be fine for low ph low tds tanks for apistos?
About 4inches worked for me. Ph should be something that suits your fish.
@@Jaysaquarium thank you so much!!!!!
@@Jaysaquarium also you mentioned in one of your videos that you lived in Korea. I'm Korean so I'm just wondering are you korean or like what? 😂
한국인입니다
@@Jaysaquarium OH SHIT FR? oh sorry. Yay me too. I can read Korean but I can't type it out on keyboard but I can write with pen and paper. Just never really had the time to learn how to type it because I'm Korean American. Oh shitttttttttt. That's nice. I used to live in Korea but don't know many people who own fish there
What is the average grain size of the sand? Also, does the bottles behind containing the sand, contain any holes?
No holes.
@@Jaysaquarium and what is the sand particle size? Is it coarse or fine sand?
River sand
first 😁
Do you also vacum clean or something ? Cause I see soo little mulm. Why is that ?
I only clean the substrate once a year.
Do you keep your tanks open or have lids on them? If open, are there any fish jumps?
I usually keep them open. It helps keep temperatures lower in the summer. fish jumping does happen. maybe once a year.
Hello, Jay. Can I do this with just pure sand? No dirt only sand? Thank you.
Yep. Pure sand is fine. Dirt helps only if you want rooted plants.
@@Jaysaquarium Cool. Thank you for the quick reply. What's your process during the first few weeks when changing water? Do you also syphon snail poop, plant debris, etc ?
Just do weekly 50percent waterchanges for 1month. I siphon a littlebit every 6months
@@Jaysaquarium Can I add Malaysian trumpet snails or is it a big no? I plan to make a deep sand bed with only epiphyte plants and some floating plants. Thank you.
Srry dont know much about snails.
Hi, just saw your videos about hydroxyde peroxide and i was wondering why doesn't algaes benefits from co2 injection like plants ?
Algae do benefit from co2. Its a matter of who benefits more.
What if it was only slow growing plants such as anubius?
Would still work. But it wont be able to handle as much.
