Tetra Crystalwater 250ml

Tetra CrystalWater safely and reliably removs dirt particles that cloud the aquarium water, making it crystal clear. It binds small particles into larger ones that can then easilty be removed by the filtration system. Tetra CrystalWater gives visible results after just 2-3 hours and will be crystal clear after 12 hours. Wait at least 48 hours before repeating the dose.
Add 5ml per 10 litres of aquarium water, this should be reduced to 2.5ml per 10 litres if the KH value is 1 or below. 250ml treats 1000 litres where the KH is above 1.
A cloud may appear shortly after using the product, this is harmless and shows that the product is working

Tetra CrystalWater can be applied regardless of the carbonate hardness value - can even be used with low carbonate hardness values. The formula contains inorganic iron salts and aluminium salts, leading to its broad effectiveness
