This was pretty cool, thanks! I would like to add a small money saver as well. If you wash the used up iron-oxide (that is saturated with phosphate) with 0.1M NaOH you can remove the phosphate and reuse the material. Don’t forget to wash away the NaOH before using it! :)
just to a couple points to add to this great video... there is also the point where more GFO is not always better. you can wipe out your tank with true 0 phosphates. try to keep just a tiny bit. also keep your your 2 part dosing AWAY from your inlet to GFO - The GFO will absorb your alk if not fully dissolved. ;)
So is tumbling bad for gfo? I didn't understand that part..mine is at a slow roll kinda like water that's beginning to boil. Just like In the video. My local fish store said that's bad and I need to put that circle sponge the reactor came with and sandwich the gfo between the two sponges so the gfo doesn't move..is this true. ? Hopefully Ryan will reply
If you don't tumble GFO, it will eventually solidify. It sounds like you have it running correctly. Your fish store might have been thinking about carbon. You do not want carbon to tumble.
What are the possibilities of doing a video on quarantine tanks? Your views on hyposalinity, copper etc. I'm torn between setting up my second tank as a frag tank or a permanent QT.
I watched your video on how to run GFO efficiently, but I have a few quedtions. What determined the rate at which GFO takes up phosphates, if I wanted to tune my GFO reactor to take out only 90% of the phosphates for example, how would I do that? Just running 90% of the recommended ammount? Or decreasing flow through the reactor? What determines how long the GFO lasts? Just flowrate? Thanks
Only in the sense that it will reduce the phosphates in the tank. If you go too far and bring the phosphates to zero, it could impact macro algae growth negatively.
I was thinking about buying a phosphate reactor and go because I think phosphate little high I got diatom on my sandbed how do you know when gfo is completed how long does it take too clear your of phosphate I have a 180
I am going to be using a canister for the first while of my tank until swapping over to a Sump when I can in which I will swap the media over and add more. That being said where or what placement should I put the gfo bag in, in the canister.
Placement won't really matter. Ideally the media would be in a reactor so that it could tumble, so just keep an eye on the media for any potential clumping.
I am starting a brand new 10 galon and I heard all I needed was purigan. I almost got chemi blu elite and purigen. Since I already ave the purigan what should I put with it? especially since algae is supposed to be common in a new tank.
You could mix in a little GFO to help keep phosphates down, but other than that, there isn't much required for filtration media. In our aquariums, most of the filtration actually happens naturally on the rocks' surface.
BulkReefSupplyCom thank you for your time to reply! I have a planted freshwater aquarium. Never had problems with brown algae (diatoms) until we moved to a rural town in Texas, the tap water here is extremely high in phosphates. I was mixing 1 part RODI water to 1 part tap water, but wanted an easier solution than dragging 5 gallon buckets to town to fill with RODI water. Thank you again!.
Jordan Sweeney Something like this, www.amazon.com/25-Foot-Python-Aquarium-Maintenance/dp/B000255NXC/ref=zg_bs_3048856011_2, I have one and it works great! Just hook to a washroom sink and turn on the water to start the siphon.
Hey! so I'm having a phosphate problem with my just finished cycled tank.. I have a biocube 14g, and my cycle is over! my ammonia and nitrites are at 0 but Phosphate is at 0.50ppm... I don't know why!!! so ccant afford a reactor. can i get a small bag and put some gfo and drop it in my first chamber which has the highest flow.. and for how long should i leave it in there for??
So, no need to use the GFO in a bag method ??? There isn't really any gunk in my tank. All i see my rocks i being brownish looks like algae , thats about it.. my sand bed is pretty clean too.
How can you tell if your gfo is clumping inside your filter bag? That might be happening in my case. I see my media basket having issues running water through it.
Thanks..i am trying my hypothesis... i have a 210 tank with 60 gallon sump. 2 months old. i have 0 ammonia and 20 ppm of nitrates but my nitrites keep bouncing from .50 ppm to under .25 ppm. Its a fish only system and i started running a gfo reactor just to keep it clean. I noticed the nitrite spike around the same time i started the reactor. about 2 -3 weeks ago. I turned it off last night ...we shall see.... the entire thing is weird.
BulkReefSupplyCom Why don't you explain the risks of completely eliminating phosphates in your videos? My first year of reefing consisted of sickly looking corals that never grew because they had no food. Your calculator prescribes WAY TOO MUCH GFO. I now use BRS GFO to maintain my phosphate levels around .02-.04 ppm and have thriving corals. This is much much better than 0.0 ppm.
Am I the only person who wants to go out to the bar drinking with this guy and just talk tanks lmao
I've run gfo since day one. AL most 3 yrs later I can say I've never had nuisance algae. Great product.
***** I just picked up *****'s GFO and Carbon reactors and within 2 days was already improving my tank. Can't wait to see what comes of my tank now.
***** Nice! Good luck.
Refer gil thank you for sharing !
We really need a video from you guys on how to safely dose Lanthanum Chloride to reduce P04 in our tanks. Thank-you!!!

how about having macro algae in your tank, such as the dragons breath algae?
would that lower the phosphate level?
I watched your video on how to run GFO efficiently, but I have a few quedtions.

What about Richard Ross's thoughts and research around Phosphate levels really not having any affect on aquarium health from MACNA?
I have sky high phosphates in my planted tank. Is there any reason why GFO would not work in freshwater, or be less effective than Phosguard?
Will gfo harm the growth of the macro algae in my refugium
Only in the sense that it will reduce the phosphates in the tank. If you go too far and bring the phosphates to zero, it could impact macro algae growth negatively.
Just love your videos do you have a supplier in the uk because good quality reef equipment is hard to come by where I live
The gfo in my reactor will not tumble. I just purchased both the reactor with the Sicce pump and the gfo. What could I be doing wrong?
What's the best location for placing your GFO Reactor in your sump?
In with your Skimmer or with the Return Pump?
I was thinking about buying a phosphate reactor and go because I think phosphate little high I got diatom on my sandbed how do you know when gfo is completed how long does it take too clear your of phosphate I have a 180
Do you ship your products to uk or do you have retailer in uk thanks
Can you put GFO in a canister filter?
where did you buy the 3155.250 rail set?
Does this help. With silicates?
GFO is primarily a phosphate reduction media. RowaPhos will remove both phosphates and silicates
I don’t have a stump can I hang it in the tank I have the Hannah one but it’s ulr and says it’s 0.90. There nuthing in tank abort from live sand
There are a few hang on back reactors that might work for you. Two Little Fishes makes a phosban reactor that I'd look into first.
@@BRStv
Amazing thankyou
ryan, I just set up rowaphos in my reactor. I had to much flow and got some of the fines in my display tank. is this bad? Thanks
really? wow I didn't know that. so I can use a magnet to clean the mess up haha. thanks.

does this work on micro algae plz?
Phosphate water pH 3,4
Can you put that in a canister filter?
Keep in mind that GFO will solidify if it sits stagnant. While you could probably get it to work in a canister filter, it wouldn't by my first choice.
I am starting a brand new 10 galon and I heard all I needed was purigan. I almost got chemi blu elite and purigen. Since I already ave the purigan what should I put with it? especially since algae is supposed to be common in a new tank.

Is it safe to use GFO in a freshwater aquarium to remove phosphates?
BulkReefSupplyCom thank you for your time to reply! I have a planted freshwater aquarium.

I was mixing 1 part RODI water to 1 part tap water, but wanted an easier solution than dragging 5 gallon buckets to town to fill with RODI water. Thank you again!.
Do you need to take the filter (carbon) out when you stick the GFO in ?
No, carbon and GFO can be run in conjunction with each other.
Will this work in freshwater setups? Just curious.
DIY Aquarium Filters Absolutely which is why it so important not to rinse with tap water as it will absorb the PO4 out of your city water.
What kinda of siphon/water changer was used in the video?

Hello, I am running your HC GFO - my phosphates test 0.25, is this a suitable level?

can too low of phosphates starve bene bacteria from reproducing?

Can we run GFO reactor during the Initial Cycling Process (new tank) , as i can see some hairy algae growing on rocks in my tank
Thank you
Thank you , but is It a good time to switch off the lights because my cycling is in diatoms (Brown algae) stage. Which is almost the end of cycle.
Thank you so much 😊
BulkReefSupplyCom hmm I always blast my lights when I cycle since bacteria blooms quicker this way.
