Reef Basis Calcium is a maximum strength ionic calcium solution designed to safely raise the calcium level in marine aquariums.

This product provides essential calcium for increased growth rates in corals, coralline algae, crustaceans and many other marine organisms. It contains no acetate, gluconates, polygluconates, silicate, phosphate or other unnecessary organics that will pollute your aquarium.

Shake bottle prior to use. Add 1 capful (5ml) per 200L of aquarium water, 3-4 times per week. For best results, measure the calcium concentration and add as required to maintain a concentration between 410 and 450 mg/L.

EXPERT USE:

Dosing through use of a drip system is a superior method of addition. Do not mix with buffers or alkalinity supplements prior to addition. You may mix it with strontium, magnesium, and many other supplements. Determine the amount of calcium consumption during the time it takes add the entire volume of your drip system. Determine the amount of Reef Basis Calcium to add in millilitres by multiplying your tank capacity in gallons by the amount you want to raise it in mg/l (ppm) and by 0.027. (Example: if you have a 100 gallon tank and you want to raise the level by 10 ppm with the entire dose, you would multiply 100 x 10 x 0.027 which equals 27 ml of Reef Basis Calcium or about 5-1/2 capfuls).
