Tap water is convenient, but the chlorine, chloramines and metals in it can stress fish on every water change. Biozym Aquastar is an all-in-one water conditioner for aquariums and fish tanks: it neutralises chlorine and chloramines, detoxifies heavy metals and helps fish maintain the protective slime coat they rely on to resist disease and stress.

Good to know:
– For both freshwater and marine aquariums and fish tanks.
– Add to the water at each change, or when setting up a new tank, to make tap water safe.
– Supports the slime coat, a first line of defence against disease and stress.
– 180ml bottle.
