Prodibio Calci Reef Plus

Prodibio Calci Reef + (10 Vials)

Prodibio Calci Reef Plus is a specially developed hydrogel supplement designed to maintain optimum levels of calcium, magnesium, and part of the alkalinity in reef aquariums. These key elements are essential for the health and growth of corals and coralline calcifying algae, which use calcium and carbonates to build their rigid skeletal structures.

Through biotransformation, under the action of BioDigest bacteria, Prodibio Calci Reef Plus releases hydrogen carbonate ions from the acetate in its calcium hydrogel, helping to stabilize alkalinity naturally. Unlike some additives, Prodibio Calci Reef Plus is gluconate-free, ensuring a clean and balanced supplement for sensitive reef environments.

When used together with Alka Reef+, this combination generates an ionic balance close to that of natural seawater, supporting a healthy and thriving reef ecosystem.

McMerwe’s comments: Prodibio Calci Reef Plus is a smart hydrogel supplement that keeps your reef tank’s calcium, magnesium, and alkalinity levels right where corals and coralline algae need them. It works hand-in-hand with your tank’s BioDigest bacteria, slowly releasing hydrogen carbonate ions to naturally stabilize alkalinity while supporting strong skeletal growth.  [Rating: 5/5]
