ReefTonic I & IIReefTonic I & II is a buffer system that stabilises the pH and alkalinity in the aquarium to match natural conditions. ReefTonic also reliably maintains the oxygen / carbon dioxide balance, which is destroyed by the metabolic processes of animals and plants. Stabilises and compensates for the calcium and magnesium used every day by the animals. Ideal used with a dosing pump.
