  Ensure that the carbonate hardness (KH) of the water is equal or higher than 6 degrees dH prior to each use. Use Tetra Pond Test to check your water values and, if the level is too low, the carbonate hardness should be increased in a controlled manner using a product such as Tetra Pond WaterStabiliser (each sold separately). Do not use to combat algae. Use Tetra Pond AlgoRem (sold separately) to combat green water (suspended algae). For best results, wait four to five days between treating the algae and using Tetra Pond CrystalWater.
