Concentrated calcium Supplement for all marine and reef aquaria
Brightwell Aquatics Calcion is a highly concentrated ionic calcium solution that increases calcium in marine water to provide corals and other reef building invertebrates with one of the most important elements required for growth.
Calcium is one of the most prevalent ions in seawater and is required for the formation or aragonite, the skeletal material of reef building invertebrates like corals, clams, tube worms etc. Seawater contain calcium levels of approximately 412 ppm. In aquaria maintaining a level of 412 to 450 ppm will enable corals etc to grow rapidly when all other physical & chemical requirements are met.
