Product details

Power Calcium provides a combination of calcium, hydrogen carbonate and trace elements for best possible biological utilisation to support healthy coral growth. The additional trace elements iron and manganese encourage the formation of important symbiotic algae (zooxanthellae), which play an important role in calcification
(Ca²+ +HCO³- -> Ca(HCO³)² - -> CaCO³ + H²CO³) of corals.

  • promotes calcification (skeleton building), particularly of SPS and LPS corals
  • supplies calcium, hydrocarbonate and trace elements in a combination for best possible biological utilisation
  • supports healthy coral growth
  • vital for stone corals, soft and leather corals, mussels, tube worms and algae
  • includes dosing spoon
  • instructions for use are enclosed

Calcium, along with alkalinity, is one of the most important parameters in the marine aquarium and is about 390 mg/l in natural seawater. The skeletons of corals (SPS, LPS), mussels (e.g. Tridacna), algae and many invertebrates (e.g. calcareous tube worms) are largely made up of calcium carbonates. Due to precipitation processes and the fact that calcium and magnesium are removed from the aquarium by being incorporated into the skeletons of different corals, the quantity concentrations and the quantity ratio of trace elements to each other change in the marine aquarium. Therefore, the supply of minerals to the reef aquarium, especially the regular replenishment of calcium and magnesium salts as well as hydrogen carbonate, plays a decisive role. The regular addition of calcium supports healthy coral growth. Each aquarium has its own requirements of calcium, magnesium and hydrogen carbonate due to the different number of consumers. The dosage should always be adapted to this consumption. The optimum calcium content in a marine aquarium is between 380 and 400 mg/l.

Power Calcium and Calcium liquid provide all calcifying organisms with the necessary mineral calcium and sustainably promote healthy coral growth. By adding Power Calcium, biologically usable calcium is immediately available to the animals in the form of calcium hydrogen carbonate (Ca(HCO3)2). One dosing spoon increases the calcium concentration by approx. 10 mg/l per 100 litres.
