Product Information

RedSea's Coralline Gro is a trace element & buffer complex that promotes the development of 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.

Coralline Gro is a complex blend of carbonate buffers, potassium and trace elements such as iron formulated in the ratio taken up regularly by the coralline algae. It should be 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 a Reef Foundation KH/ Alkalinity Pro test kit.

Important Notes:

  • Before carrying out any water testing always check the salinity and make
    adjustments as necessary. If you have made adjustments to the water wait 10
    minutes for the water parameters to stabilize.
  • Test only with high resolution test kits such as Red Sea's Alkalinity Pro Titration Kit.
  • Red Sea's Coralline Gro supplement has a dosing chart based on treating 100 liters
    / 25 gallons of water. Estimate your total volume of water (aquarium & sump less
    volume of live rocks etc) to calculate the correct dosage for your system.
  • Supplements should be added to the sump. If you do not have a sump, add the
    supplements slowly to an area with high water flow to prevent direct contact with
    the corals.
  • To prevent stress to the corals the maximum daily change of alkalinity should be no
    more than 0.5 meq/l (1.4 dkh)
  • 1ml will raise the Alkalinity level of 100 liters (25 gal) by 0.1 dKH (0.03 meq/l).
