Supplements

Supplements or additives for coral reef aquariums replenish elements found in natural seawater vital for sustained coral growth and overall health. Calcium, alkalinity, and magnesium are the most popular supplements used by reef hobbyists.

Before beginning any supplementation regimen, always test your aquarium for the particular element you wish to supplement to establish a baseline. Be sure to test, monitor, and record aquarium parameters before and after supplementation to ensure proper levels.
