Product Description

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. KH 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. KH 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. KH Coralline Gro should be dosed according to a measured drop in alkalinity with Red Sea's Reef Foundation KH/Alkalinity Pro Test Kit. Concentration: Liquid supplement: 1ml will raise the Alkalinity level of 100 liters (25 gal) by 0.1 dKH (0.03 meq/l).

5.0 out of 5 stars Red Sea makes great product.

Red Sea makes great product. I have been using their additives for some time now and recently purchased a Nano Max. I call this the "purple up" might be the name of another product but this is what the does for the tank. I have used it in multiple systems including this new tank, the coralline algae is taking off. This tank is a bare bottom tank and will look great along will all the rock in there. I dose this in a large and older system and it has also improved growth. [ reminder this will compete with coral in the tank for elements with-in the water]

4.0 out of 5 stars Moderate Coralline Growth
Reviewed in the United States on July 23, 2016

I've used this as a buffering additive to all my tanks with minimal coralline algae growth. It does seem to buffer the PH with little longterm effect on KH. Like other buffering additives, though, it only raises the PH for a short time. I use it regularly while also dosing Red Sea Foundation Part B (for ALK) with rare KH elevations.

2.0 out of 5 stars Precipitates immediately
Reviewed in the United States on June 14, 2014
Verified Purchase
I am not sure what baseline tank chemistry this is designed for, because on both my large reef tank and my nano tank, this supplement precipitates immediately. I get lots of little white specks floating around, and probably very little dissolves in solution. I also tried this on both tanks after performing large water changes so the reef water parameters were close to ideal. That still results in major precipitation. I didn't see an increase in coralline algae growth.
