Sera Kh Test Kit

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

• In the case of too low KH values we recommend Sera KH/pH-plus (in freshwater) or sera pond bio balance (in ponds)
• In the case of too high values we recommend filtering through Sera super peat (in freshwater aquariums)
• Makes it easy to monitor the carbonate hardness in fresh and salt water
