Phosphates are going to be one of the biggest battles we have with a reef aquarium. The BRS GFO works even better in reactors due to it being denser than most other GFO. The price is just about double of standard GFO however you only need to use half as much which equals out in the long run. High Capacity is going to have less dust than almost all other GFO on the market and being able to buy it in bulk saves a ton of money.
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.
Two Types of GFO:
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 take hold, it can be a difficult battle but it is winnable. The best offence against algae is to take preventative measures and attack nutrient before an outbreak is apparent.
