Biozym Nitrifying Probiotic Pro adds a strong dose of the beneficial bacteria that turn ammonia and nitrite into nitrate — the core of a stable nitrogen cycle in any aquarium or fish tank.

It is a handy shortcut when cycling a new setup, and a good reset after a big water change or a course of medication has knocked the biofilter back. Dose it into the tank or filter and the colony gets to work.

Good to know:
– Concentrated liquid nitrifying bacteria culture.
– Helps keep ammonia and nitrite in check while the filter matures.
– Safe for fish, shrimp and plants.
– Available in 300ml, 500ml and 1000ml bottles, from nano tanks to large setups.
