Bio-Actif Pro-Coral Kalk 28 oz (800g)

Bio-Actif Pro-Coral Kalk
Manufactured by Tropic Marin

Tropic Marin's Bio-Actif Pro-Coral Kalk increases pH and calcium content to promote healthy corals and faster growth of beneficial calcareous coralline algae. Also, by binding carbonic acid, one of the inevitable by-products of operating a CO2-calcium reactor, it will inhibit the growth of undesirable algae.
