Ubbink Alkalinity Booster Aqua GH/KH Plus 500 g
This Ubbink Aqua GH/KH Plus alkalinity booster offers immediate help in case your pond water has a low general hardness (GH) or carbonate hardness (KH). General hardness (GH) and carbonate hardness (KH) represents the main "buffering capacity" of water, i.e. its ability to resist pH changes. If KH is too low the pond water pH will be less stable and the fish and plants will be harmed by rapid changes in the pH. By adding Aqua GH/KH Plus, the carbonate that leaches into the water will restore the buffer system by basically neutralising any excess amounts of H+ or OH-, ensuring a balanced GH and KH level.
