RedSea's Coralline Gro is a trace element & buffer complex that promotes the development of Coralline Algae.
Coralline Algae: Coralline Algae will grow naturally, without any special supplements in all reef systems optimized for hard corals. To promote coralline algae in fish only or soft coral aquariums the alkalinity needs to be maintained at approximately 3 meq/L ( 8.4 °dKH ) and specific minor and trace elements need to be readily available. This can be a problem when running a Berlin system as this coats the porous live rock which the bacteria needs to thrive and duplicate.
About RedSea's Coralline Gro Live Rock Vitalizer: Coralline Gro is a complex of carbonate buffers, potassium and trace elements such as iron formulated in the ratio taken up regularly by the coralline algae. Coralline Gro should be used instead of Reef Foundation B (buffer) supplement during the cycling of all new marine aquariums and on an ongoing basis in fish-only or soft corals systems. Coralline Gro should be dosed according to a measured drop in alkalinity with Reef Foundation KH/ Alkalinity Pro test kit. It contains specific elements required for the active development of Coralline Algae.
