Tetra CrystalWater

Tetra CrystalWater treats and purifies aquarium water safely and reliably. It is suitable for all carbonate hardness values. Suspended and cloudy particles are bound and then removed from the water by the aquarium filter. The formula contains inorganic iron and aluminum salts that prevent any risk of toxicity. Tetra CrystalWater starts to take effect after 2-3 hours and the water is crystal clear after 6-12 hours. For optimum results, we recommend using it together with AquaSafe and EasyBalance. Only suitable for fresh water.
