Key Features


Keeping control of the calcium levels in a marine aquarium is imperative for the health and growth of the corals and other invertebrates inside.

If the concentration of calcium is too low it will cause the growth rates to suffer. However if the levels are too high the vital alkalinity and buffering capacity will also be greatly diminished leading to the possibility of instable pH levels.

Reef Basis Calcium is a high quality maximum strength ionic clacium solution. It is designed to safely raise the calcium levels in marine aquariums, thus providing this essential chemical for increased growth rates in organisms like coral, coraline crustaceans and many others.

It is a safe compound as it contains no acetate, EDTA, gluconates, polygluconates or other unnecessary organics to pollute your aquarium. It is phosphate and silicate free. May be used simultaneously with Kalkwasser.


It is recommended that you maintain a calcium level of between 410 and 450 mg/L (ppm), an alkalinity level of 7 to 11 dKH (2.5 to 4 meq/L), and a magnesium level of 1250 to 1350 mg/L (ppm).

Note: Aquarists keeping SPS corals should consider keeping alkalinity at 7 to no more than 9 dKH (2.5 to 3.21 meq/L). Do not add calcium and buffering (alkalinity) products at the same time. Doing so will cause unnecessary precipitation and possible cloudiness.


250ml treats up to 2080 gallons Shake well prior to use. Add 1 capful (5 ml) per 41 gallons (200 L) of marine aquarium water 3 to 4 times per week.

For best results, measure the calcium concentration and add as required to maintain the concentration between 410 and 450 mg/L.
