Red Sea KH Coralline Gro is a specialized marine supplement designed to promote the growth of vibrant pink and purple coralline algae. Unlike standard alkalinity buffers, this formula is a complex of carbonate buffers, potassium, and specific trace elements such as iron, formulated in the exact ratio taken up by coralline algae. By maintaining the correct alkalinity and delivering essential micronutrients, it helps coralline algae outcompete nuisance hair algae, creating a more natural and aesthetically pleasing reef environment.
The Red Sea KH Coralline Gro provides a dual-action approach to reef chemistry by stabilizing $pH$ while fueling encrusting algae.
Dual-Action Formula: Acts as a high-quality Alkalinity (KH) buffer while simultaneously delivering the specific trace elements needed for coralline pigmentation.
Algae Competition: Rapid coralline algae growth covers live rock surfaces, preventing the attachment and spread of invasive green hair algae or film algae.
Enhanced Coloration: Contains specific forms of iron and other micro-elements that intensify the deep purples and pinks of crustose coralline algae (CCA).
Ionic Balance: Designed to work as part of the Red Sea Reef Care Program, ensuring that your trace element levels remain balanced with your major foundation elements.
Easy Dosing: Available in a concentrated liquid format that can be dosed manually or via an automated dosing pump.
Should I use this instead of a regular KH buffer?
Use this during the cycling or maturing phase of your tank to establish coralline algae. Once your tank is heavily stocked with stony corals, you may want to switch to Red Sea Foundation B (Alkalinity) to avoid overdosing the trace elements included in Coralline Gro.
How much should I dose?
The standard dose is 1ml per 100 liters (25 gal) daily, which will raise your alkalinity by 0.1 dKH. Always monitor your alkalinity levels and adjust the dose to maintain a target of 8.4 dKH.
Does it work in tanks with low Magnesium?
Coralline algae require magnesium to plate. If your magnesium is below 1300 mg/L, you may see poor results even with Coralline Gro. Ensure your Magnesium and Calcium are in the optimal range first.
Will this make my water cloudy?
If dosed into a low-flow area, temporary cloudiness may occur as the carbonates react. Always dose into a high-flow area of the sump or display.
