SuperBioGravel Media was developed specifically for Shower filters, although I suspect it’s outstanding characteristics will make it a great choice for a wide variety of filters. Like BioGravel, SuperBioGravel is an extremely dense media. You can pack a larger volume of media into any given space because of its spherical shape.
1 kg occupies only 57 cu in. The balls range in size from about 3/8″ to 1″. Click on the link, “How Much Do I Need” to see how much your filter requires
Like all Biohome media it has a extremely porous structure to better support a large number beneficial bacteria. Complimentary Filter Starter Balls (1/4 Bag per Kilogram) are shipped with each order.
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.
SuperBioGravel 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.
