- Highly-concentrated ionic calcium solution
- Increases the concentration of calcium in marine aquarium water to provide corals and other reef-building invertebrates with one of the most important elements required for growth
- Is ionic rather than chelated, and contains no unwanted organic material such as EDTA, gluconate, or polygluconate
- Over 50% stronger than most competing products
- Free of phosphate, silicate, and organic material
- Formulated by a marine scientist
- Calcium is one of the most prevalent ions in seawater, and is required for the formation of aragonite, the skeletal material of reef-building invertebrates such as corals, clams, tube worms, and their respective allies. In seawater, calcium is present at a concentration of approximately 412 ppm; in reef aquaria, maintaining calcium within a range of 412 - 450 ppm will enable corals and other reef-building invertebrates to grow rapidly when all other physical and chemical requirements are met. [Magnesium, strontium, and carbonate ions are also complexed into aragonite, and their importance in a reef aquarium cannot be overstated.]
The rate at which calcium is extracted from the water is determined by the stocking density of reef-building livestock, type of lighting, and other biological, physical, and chemical conditions; therefore, each aquarium will have different requirements for the rate of calcium supplementation. Once the rate of calcium uptake in the aquarium has been determined (see opposite), the proper dosing rate of this product can be easily calculated.
It is recommended that a quality salt mix with the proper (not augmented) alkalinity and concentrations of major, minor, and trace elements be used to establish natural seawater parameters in the reef aquarium, providing a stable ionic foundation on which to build.
All Brightwell Aquatics liquid water care supplements are made with purified water and high purity materials. They develop formulae for aquaria based on empirical data, using observation and measurement rather than theory.
