BioGravel media is the ideal substrate for your tanks. Sintered glass is mixture of silica sand and recycled glass fired at high temperature to form rough, porous glass balls. Nearly inert it should not affect pH significantly, although a large volume may raise the pH temporarily.
It supports growth of zooplankton and is the perfect playground for shrimp. It should also work well in small DYI, internal, HOB and canister filters.
BioGravel media is also an ideal filter media. The dense BioGravel allows you to pack more media into a given space than any other variety. All of the GreatWave Endless River Koi Pond Filters are now filled with BioGravel. To see how much your filter requires return to the Home page and click on the link at the top, “How Much Do I Need“.
BioGravel is a small, round media ranging in size from 1/8″-1/4″ in diameter. 1 kg occupies about 56 cu in.
Complimentary Filter Starter Balls (1/4 bag per kg) are shipped with each order to speed beneficial bacteria growth. The media recovers quickly after the use of medications.
Biohome ® allows both nitrifying (aerobic) and denitrifying (anaerobic) bacteria to grow on and through it’s unique structure. This allows it to also control nitrates. Check the Rules of Thumb for Nitrate Reduction to estimate how much you’ll need to reduce the nitrates in your pond or tank.
Biohome ® BioGravel 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.
