Continuum Aquatics Reef Basis Calcium - Calcium Powder for Marine Fish and Reef Saltwater Aquariums, 800 g (QCALD800)

Reef Basis Calcium is a high purity calcium in dry form, designed to safely raise the calcium level in marine aquariums, providing essential calcium for increased growth rates in corals, coralline algae, crustaceans and many other marine organisms. 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. Proper control of calcium level is imperative for the health and growth of corals and many other invertebrates. If the calcium concentration is too low, growth rates will suffer. If it is too high, alkalinity or buffering capacity will be diminished, leading to possible instability of pH. Sufficient magnesium levels are also necessary to maintain the proper balance. It is therefore recommended that the hobbyist measure and control the levels of calcium, magnesium and alkalinity on a regular basis. Strontium is also required for formation of aragonite. Continuum recommends 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.
