Top-up and water change guidance

Use Mr Koizumi Subarashi Detox before untreated source water can affect fish or biological filtration. New water should be added at a sensible rate, especially on koi ponds, so temperature, pH and chlorine/chloramine changes do not shock the system. For purifier cartridges or carbon units, replace media when capacity is reached rather than relying on old exhausted material.
