Customer Review

In the beginning I have made regular water tests, but that has subsided quickly, as can be seen also by common sense and routine, if a water change is present or not. Meanwhile, the use-by date has expired and the case is still half full. Water can also be in the pet shop test lassen.Tests you can also buy separately. What do I need occasionally, KH, PH 6 to 7.6 is. Very rarely: NH4, NO3. And the book Handbook of aquarium water.
