Coralline Gro, Live Rock Vitalizer is a trace element and buffer complex that promotes the development of coralline algae. It contains specific elements required for the active development of coralline algae in all marine systems. Coralline Gro should be used while cycling new systems and continuously in fish only or soft coral aquariums. Coralline Gro can be used instead of Reef Foundation B to maintain alkalinity at 3.0 meq/l (8.4 dKH). Do not use Coralline Gro together with Red Sea's Reef Color B and Reef Color C supplements as they may cause overdosing of specific elements.
