Alkalinity (carbonate hardness) is critical to aquarium and coral health. Adequate carbonate levels are essential if corals are to thrive and grow, while aquariums with insufficient alkalinity reserves can also suffer from excessive swings in pH. TheReef® Alkalinity is a concentrated solution of carbonate ions that can be readily utilised by corals and other marine organisms. Guidance: First measure alkalinity levels in your aquarium with an accurate test kit to determine how much of TheReef® Alkalinity supplement you should add. We recommend maintaining alkalinity levels between 7.8-9.0 dKH. 15ml (1 capful) of supplement per 100 litres of aquarium water should raise calcium levels by around 1dKH. Shake bottle before use then slowly add required quantity of supplement to an area of aquarium or sump with high flow. Do not raise levels by more than 2dKH a day. Do not mix with or use within 1 hour of other supplements. Store above 10°C.
