Very Satisfied By Charlotte Reefer on 3/10/14Charlotte Reefer would recommend this product to a friendI'm running the GFO high capacity with an IM Minimax reactor on my nuvo 24 tank. I was getting some nasty hair algae after trying to fatten up some new fish. PO4 was around 0.08 and that was with Chemipure Elite in the media basket. After a few days by phosphates went down to 0.03 and last night I registered 0.00 using the Hanna low range checker. CUC is destroying the algae now and it take about 3 days before I get a noticeable green/brown film on the glass.
This seems to be a great value. Given the size of my tank and the rate the GFO is being used up, this is pretty affordable way to control phosphates. I highly recommend.
Great product By Ourisland42 on 2/20/14Ourisland42 would recommend this product to a friendI would definitely recommend. It is working !! My phosphates are going down, finally....
Excellent service with BRS, as always!
Phosphate Removal By Matt on 2/17/14Matt would recommend this product to a friendWorks great at controlling phosphates. Also, works well in a media reactor as I use it with the TLF media reactor with a maxi-jet pump.
Must have for any reef tank By James on 1/25/14James would recommend this product to a friendI've been using the brs standard gfo and this gfo makes a huge difference. I couldn't keep my phosphate under .06 with the standard stuff. Now I've got it down to .01 in only the first week of using this product! I'm very happy even though it's a little more money.
Must buy! By devon on 1/10/14devon would recommend this product to a friendi really love this media, i have seen drastic changes while using this. i tends to last long than the cheaper stuff. less dust is a big plus. i must say though what until it is on sales thats when i order it.
phosphate killer By Theodore on 1/6/14Theodore would recommend this product to a friendThis gfo took my phosphates from .5 to undetectable . Amazing stuff now my corals are way more colorful and polyps are fully extended. Couldn't be happier with this product.
Excellent fast phosphate killer! By George on 12/29/13George would recommend this product to a friendBRS' standard gfo is amazing... but this... this takes it to another level. My square 60 gallon salt tank was fill to the bring of slimy green algae. My brother then took this stuff... put it into my two reactors i recently bought and within a week the green disappeared. After 2 months, the water has remained crystal clear. The best time to get this is during their sale which is what we did during their black friday sale. Can't go wrong. Double the power of the standard stuff no joke!
GFO that makes a differemce By terminator on 12/3/13terminator would recommend this product to a friendI have used many different types of phosphate removal products and for cost, quanity and effectiveness you can't beat the high capacity version of this GFO. There are a few other products that are as effective but cost more and you get less of it. Why spend more?
This is the only practical GFO to use, hands down
Tank is looking better after only days By Geo on 11/20/13Geo would recommend this product to a friendOur LFS ran out of RowaPhos and it was going 3 weeks, I tried other gfos but they didn't do it, too much dust or they would just clump and not tumble, gave the high capacity a go and my tank is already looking better. I believe I will be sticking w this from here out.
works great By jim on 11/18/13jim would recommend this product to a friendez using, little dust.starts cleaning real fast.
Great Product By MICHAELO on 9/30/13MICHAELO would recommend this product to a friendVery well constructed and easy to change canisters, mounting option is cool. Makes use of space and utilizes 2 separate elements for individual change, Bottom line is, it makes life much easier! If you have a need for these elements then you have a need for this item.
Saves space in the sump By GainesvilleReefer on 8/8/13GainesvilleReefer would recommend this product to a friendBy using this over the regular GFO I was able to mix with the ROX carbon and fit in one reactor.

Will this work in a phosban 150?
Bulk Reef Supply Hey Jeff,
It sure will. Its a great combo if you need something that is hang on back!

Does the high capacity GFO have to be tumbled in a reactor or could I place it in a media bag and put it in a high flow area of my sump?
Bulk Reef Supply Hey Kevin,
It is best when tumbled in a fluidized bed reactor as the media otherwise has a tendency to harden into a brick, but even placed in a filter sock would be better then nothing.

Can I use the high capacity in a small tank (30 gallon)?
Bulk Reef Supply Hey Scott,
There isn't any minimum size limit to the high capacity gfo. It can be used in any aquarium it just happens to be more popular in larger tanks because you don't need as much media. Its handy when your trying to keep the equipment smaller while still maintaining the same effect.

what is the amount of GFO HC you would normally run in a 120 gallon reef?
Bulk Reef Supply They there,
For a tank that size you would want to run 1 cup of GFO. The easiest way to do the math is to use the BRS Calculator right here:

How much do u start out with in your reactor? Is there a measurement per gallon ratio?
Bulk Reef Supply Hi Brandon,
It depends on how large your tank is. The easiest way to do the math is to use our reef calculator at the link below. You enter the size of the tank and the type of GFO you want to use, it will tell you how much GFO to add.
Two Types of GFO:
- Granular GFO is varied in its shapes and requires the least amount of flow to tumble. Good for reactors.
- High Capacity GFO is twice as dense as Granular GFO, so twice as much material will fit into a reactor. It's extremely hard and has less dust to begin with. Fewer fines will be created during use and transportation. By volume, High Capacity GFO will remove roughly twice the phosphate compared to the same volume of Granular GFO. Best overall performance.
Special note on fighting existing algae problems: Algae needs three main nutrients to grow: phosphate, nitrate and light. Reducing any one of these will significantly slow down algae growth but may not completely solve your issue. Once algae takes hold, it can be a difficult battle but it is winnable. The best offense against algae is to take preventative measures and attack nutrient before an outbreak is apparent. Use the following suggestions and be aggressive if an algae problem is already present:
- Maintain undetectable phosphate levels with good feeding habits and use a phosphate remover like GFO. 99% of all phosphate is added to the tank via foods.
- Control nitrate levels by reducing feedings, increasing the water change schedule and maintaining a properly sized protein skimmer.
- Use nutrient free RO/DI water for water changes and top off water
- Shorten your lighting period or intensity. In some cases aquarists have found replacing old bulbs that have fallen out of their intended spectrum helps as well.
- Continuously remove as much algae as possible by hand.
- Add predators - nothing helps an algae outbreak as much as critters who eat it all day long. Various tangs, lawn mower blennies, crabs and snails are all good options. It is also theorized that a healthy pod population will also control algae growth before it gets a chance to take root.
