Easy-Life pH Buffer is a strong and concentrated blend to raise the KH and stabilize the pH at the correct level. In time, a marine or reef aquarium will lose its carbonate hardness (KH), which may lead to a dangerous acidity level (pH value).Dosage Easy-Life pH Buffer KH+:1 measuring spoon (about 5 ml product) per 50 litres raises the KH 3.4 to 3.8 dKH. First dissolve the powder in freshwater (1 spoon per 200 ml) and raise the KH of the saltwater slowly. A measuring spoon is included.
