Carbonate hardness (KH) helps stabilize the pH level, which is vital for fish and plant health.
Low KH levels can lead to dangerous pH fluctuations.
✅ Enough for approx. 390°dKH
💡 Recommendations:
-
Low KH? → use sera KH/pH-plus (freshwater) or sera pond bio balance (ponds)
-
High KH? → filter with sera super peat (freshwater aquariums only)
