Sera kH Test Kit - monitors Carbonate Hardness in Water

Makes it easy to monitor the carbonate hardness in fresh and salt water

For approx. 390°dKH. In case of too low KH values we recommend sera KH/pH-plus (in fresh and marine water) or sera pond bio balance (in ponds), in case of too high values we recommend filtering through sera super peat (in freshwater aquariums).
