SF CRYSTAL MAX 10L

Superfish CrystalMax Bio is a biological material that allows you to maximize the performance of the space available in your filter. Thanks to its special production (sintered glass), CrystalMax offers an extremely porous surface for denitrifying bacteria. If you want to speed up the maturation process, we recommend pouring freshly purchased bacteria, ideally gel and liquid, together with a bacterial activator, along with a little pond/aquarium water. Thanks to its special sponge-like effect, Crystal Max sucks up the liquid containing the bacteria!
