  • Remove phosphates from your tank with Granular Ferric Oxide

Quick Overview

High Capacity GFO is the best performing GFO we stock and capable of removing close to twice the phosphate as standard GFO by volume. We recommend this when you have a large tank or limited room in your media reactor.


Granular Ferric Oxide (GFO) removes phosphate from the aquarium and is one of the most commonly used filtration media used in the aquarium industry.  GFO is one of the few ways to easily maintain ultra low phosphate levels on a consistent basis. Maintaining these ultra low levels will help prevent algae outbreaks as well as treat existing algae issues. Your aquarium's glass will also stay clear and free of the green hue significantly longer. GFO is most commonly used in a media reactor like the BRS reactor or media bag.


Phosphate inhibits proper coral growth by incorporating itself into the corals skeletal structure which makes it difficult for the coral to grow by laying down additional calcium and carbonate (alkalinity) ions. Maintaining ultra low phosphate levels will increase the growth of any SPS or LPS coral.


Algae outbreaks are one of the most common reasons for a complete tank shut down. We recommend preventing them by maintaining an ultra-low nutrient level environment where it would be difficult for them to get out of control to begin with. It is much easier to prevent outbreaks than it is to treat existing outbreaks.

Product Questions

will this product leach phos back in the tank?
Question by: Eddie on Apr 21, 2014 5:05:00 PM
Hi Eddie,
It will not release back phosphates under aquarium conditions.

How much do u start out with in your reactor? Is there a measurement per gallon ratio?
Question by: Brandon on Oct 4, 2013 12:46:00 PM
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.

what is the amount of GFO HC you would normally run in a 120 gallon reef?
Question by: Skopp on Oct 15, 2013 3:19:00 PM
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:

Can the HC GFO tumble more than the standard, higher flow? I am also using the filter pads on the top to help keep the particles in better. Your thoughts would be great.
Question by: Chad on Jul 7, 2014 2:50:00 PM
Hi Chad,
The GFO HC is a denser/harder product which means it can handle more flow without breaking down (though at the same flow, its tumbling characteristics would be about the same). If you are trying to increase flow you could also remove the sponge pads in the reactor when using GFO.

Will this work in a phosban 150?
Question by: Jeff on Nov 29, 2013 9:32:00 AM
Hey Jeff,
It sure will. Its a great combo if you need something that is hang on back!
Answer by: Bulk Reef Supply on Nov 29, 2013 9:32:00 AM
Will this product also remove silicates?
Question by: Ron on Jun 5, 2015 4:34:00 PM
That is a great question!
GFO will help to remove silicates from the water slightly. It sole purpose however is for phosphate removal.

How many cups are there in the 1/2 Gallon (3.5 lbs.) of HC GFO?
Question by: Adam on Feb 6, 2015 5:36:00 PM
Great Question Adam!
There will be 8 cups in a half gallon container.
Answer by: Bulk Reef Supply on Feb 6, 2015 5:36:00 PM
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?
Question by: Kevin on Oct 10, 2013 10:31:00 AM
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.
Answer by: Bulk Reef Supply on Oct 10, 2013 10:31:00 AM
Can I use the high capacity in a small tank (30 gallon)?
Question by: Scott on Sep 1, 2013 8:58:00 AM
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.

Full Details

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.

  • Seems pretty great By Damon on 6/10/2015

    Virtually no dust so rinsing is quite fast. Fluidizes very well and doesn't seem to break down like RowaPhos... Also seems to pull a bit more phos compared to RowaPhos but not sure if this is fact or perception. Overall, I like it!
  • Works Great By Brian on 4/28/2015

    I use this for phosphate removal on both my 150 reef and my 65 gallon predator tank. I usually change it out every 6 weeks and use a reactor for it. I check my phosphate's weekly using a Hanna checker and rarely do I get anything above a .02.
  • Good stuff By John on 4/11/2015

    Seems to remove a little less PO4 than ROWAphos, but is much easier to use. Not much dust when rinsing before use. Works well in BRS deluxe reactor, slightly fluidized, without the sponges installed. Just started regenerating it, which seems to work well.
  • Good product By Tripp on 4/1/2015

    Using the high cap GFO. Can't compare it to standard, but it is very effective in PO4 removal. Definitely use a small amount when starting out. I used 1/2 of the recommended starting amount and built up slowly from there. Didn't have any issues
  • FRICKIN AWESOME By Wrath of Poseidon on 3/6/2015

    i have lots of fish lots of corals in a 150g can go 2 months with out what changes
  • Very Happy By Benjamin on 3/5/2015

    Been running the HIgh Capacity GFO for two years in two different tanks. On my 90gal. I have the BRS dual reactor with GFO and Carbon. Since running the HIgh Capacity GFO, my phosphate levels are non existant.
  • GFO high cap By Mr. Fish on 3/5/2015

    Great product love it!
  • Solid Product By MarkO on 2/28/2015

    Works. Noticeably higher capacity than regular GFO. Not sure how much, however.
  • Easy and efficient! By Tony on 2/26/2015

    Using with a mix of Rox carbon in my Deluxe BRS reactor and ran clear almost instantly!
  • Great start By Ken on 2/14/2015

    Its the perfect size to get your new GFO reactor off to a great start
  • Great product, but a bit $$ By Submerge on 2/4/2015

    You get what you pay for. This GFO works well in a bag in the sump. It doesn't clump if kept in a high flow area. I just massage it around every few days for "general principle". It does a great job at keeping the phosphates low, about 1/10 of what they were before.
  • Amazing product! By David on 1/14/2015

    I was continuing to have issues getting my Phosphates down to a negligible amount. I was dosing all sorts of products in an attempt to get the counts down. I installed a BRS Reactor with High Capacity GFO and crossed my fingers. I installed it three days ago and today my reading was 0.05! I can't say enough positive things about this product. Thank you BRS!
