Product details
ME Coral Calcium Powder is a calcium additive for marine reef aquariums, designed to help replace the calcium (Ca) that corals and other calcifying organisms consume over time. This USP-calcium chloride dihydrate powder comes pre-measured to mix into a ready-to-use liquid solution, supporting practical, consistent 2-part style aquarium calcium/alkalinity maintenance. For reference-level guidance, many reef keepers aim for a calcium range of about 400–450 ppm, and test frequently with a reliable aquarium test kit.
Features:
- Premeasured powder designed to mix into 1 gallon of liquid solution with RODI water
- Made with pharmaceutical grade USP Calcium Chloride Dihydrate Powder
- Ammonia, phosphate, and nitrate free
- Designed to dissolve quickly to form a clear solution with no residual impurities by room temperature
- Useful for either dosing pumps (often as part of a 2-part system) or manual additions
- Best results are achieved when used in conjunction with ME Coral Alkalinity to maintain balanced daily supplementation
