Calcium-Max is the cationic counterpart to Alkalinity-Max.
It consists of all the major and minor cations that constitute total hardness. Calcium is the major hardness ion. It alone makes up to 50,000 mg litre. The balance of the cations are: Magnesium, Strontium and Barium. These elements along with potassium, Lithium and Boron and other cationic trace elements are proportioned to imitate the same ratios, with respect to Calcium, as found in natural oceanic seawater.  Each litre combination of Calcium-Max and Alkalinity-Max can produce 125g (4.5oz) of calcareous growth.
Suggested starter dosing: 50 Gallon (227 litre) aquarium. 1mL solution per 4 Gallons (18 litres) of aquarium water
12mL Calcium-Max part A
12mL Alkalinity-Max part B

Alkalinity-Max is the anionic counterpart to Calcium-Max.
It consists of the elements that contribute to total alkalinity.
Carbonate, Bicarbonate and Hydroxide alkalinity are the major ions. They make up 2,500 milliequivalents of alkalinity per litre. Along with these anions are also, Sulphates, Bromides, Fluorides, Iodides and other anionic traces, all in proper ratios with the respect to total alkalinity. 

Dose this product in an area of the aquarium or sump of high water movement to aid dispersal and dose both parts simultaneously. Allways check water parameters before dosing with a reliable and accurate test kit and never add more than 1ml per gallon in a 24 hour period.
