16mm Aquarium Filter Media Plastic Bio Balls (50Pcs)
50 Pieces of Plastic Bio-Balls for Maximizing Biological Filtration Within Your Tank
Place this media in a sump, external, or hanging filter to grow nitrifying bacteria that naturally convert ammonia and nitrite.
Plastic balls are designed specifically to increase the surface area so that more beneficial bacteria can grow. They aren't as porous as clay, however, this keeps them from clogging as much. Clean every so often when you regularly do a water change and rinse in aquarium water as the chlorine in tap water can kill the bacteria.
Bio balls can be used with both saltwater and freshwater tanks and, in general, 2.2 gallons of bio balls to 100 gallons of water is the recommended amount needed for maximum filtration.
