Maintain stable and healthy water conditions with Sera KH/pH Plus 2.5L — a professional water conditioner designed to safely increase carbonate hardness (KH) and stabilize the pH value in freshwater aquariums and garden ponds.
Low carbonate hardness can cause sudden and dangerous pH fluctuations, commonly known as a pH crash, which can stress or even harm fish and beneficial bacteria. Sera KH/pH Plus safely raises carbonate hardness, helping to stabilize the pH level and create a balanced aquatic environment.
By improving the buffering capacity of the water, this conditioner supports healthy biological filtration, encourages beneficial bacterial activity, and promotes the overall wellbeing of fish and aquatic plants. It is ideal for routine water maintenance, after water changes, or whenever KH levels are too low.
