BRS Bulk GFO Granular Ferric Oxide – High Capacity (About 5 lbs or 80 oz left)

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 BRS stocks and capable of removing close to twice the phosphate as standard GFO by volume. BRS recommends this when you have a large tank or limited room in your media reactor.
