Glaxo Stone Ultra Amtra 300ml / 150 lt

GLAX STONE ULTRA are stones in sintered clay, ideal for the establishment of fundamental microorganisms for biological filtration.

It is a high-performance filter material that effectively supports the aquarium cleaning cycle, which can be fresh or marine water. Only 1 liter of product offers bacteria a settlement surface of 600 m²! Thanks to the large area given by the high size of the cavities for the settlement of bacteria (from 10-500 μm), even long chain polluting molecules are securely tied, cleaning the water of the aquarium in depth. Furthermore, the product not only breaks down ammonia and nitrites, but also reduces nitrates. GLAX STONE ULTRA supports the entire aquarium cleaning cycle, both aerobic and anaerobic one.
