Concentrated powdered Calcium helps maintain and increase your tanks Ca level without increasing any other elements concentration. Calcium is an essential part of calcification and coral growth. Corals skeletons are dependent on having ample calcium and alkalinity in the water for corals to absorb and convert into a calcium carbonate structure. Dry Calcium additives are very cost effective and when mixed into a solution can be just as good or better than liquid additives. Aquaforest Calcium Dry can be mixed with Magnesium Dry to create a solution that when dosed will maintain proper calcium and magnesium levels with a single dosing pump.


Calcium Dry can be used with:

  • SPS corals
  • LPS Corals
  • Soft Corals
  • Clams


Two Sizes Available:

  • 1000 g
  • 4000 g

  • It is suggested to start with a dose of 5mL per 27 gallons of aquarium water daily. After each dose, test your aquarium's Calcium level and adjust dosage as necessary for your systems requirements.
  • It is highly recommended to add calcium solution slowly to a high flow area of the tank to help reduce any precipitation.
