GlaX Stone Ultra Amtra 300ml /150 lt

Glax Stone Ultra are sintered clay stones, ideal for the installation of microorganisms that are fundamental for biological filtration.

It is a high performance filter material that effectively supports the aquarium cleaning cycle, which can be fresh water or marine. Only 1 litre of product offers bacteria a settlement surface of 600 m2! Thanks to the wide surface given by the high cavity size for the installation of bacteria (from 10-500 μm), long-chain pollutants are also securely tied, cleaning aquarium water deep. In addition, the product not only breaks ammonia and nitrites, but also reduces nitrates. Glax Stone Ultra supports the entire aquarium cleaning cycle, both aerobic and anaerobic.
