Biohome Ultimate Filter Media

The name says it all. This is the Ultimate media for canister, HOB and sump filters. Biohome Ultimate supports beneficial bacteria growth. Bacteria growth in Ultimate is very fast to control ammonia and nitrite. Complimentary Filter Starter Balls (1/4 bag per lb) are shipped with each order to speed filter maturity. It recovers quickly after the use of medications. The media allows both nitrifying (aerobic) and denitrifying (anaerobic) bacteria to grow on and through it's unique structure. This allows it to also control nitrates. Ultimate Media is a biological filter media and good mechanical filtration must be provided to insure the water passing through it does not contain any debris that might clog it.
