Biozym Crystal Water is a fast-acting water clarifier for aquariums and fish tanks. Cloudy water is usually fine suspended particles the filter cannot catch on its own; Crystal Water binds those particles together until they are heavy enough to settle or be filtered out, clearing the haze and putting your display back in focus.

It does not upset the biological balance while it works, so you can dose it as part of a normal maintenance routine.

Good to know:
– Clears cloudy or milky water caused by suspended particles.
– Safe to use with fish, shrimp and plants.
– Works with your filter, not against it.
– 500ml bottle.
