Red Sea KH Coralline Gro

Red Sea

Red Sea 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.

Coralline Gro should be used instead of regular buffer supplements (such as Red Sea’s Reef Foundation B) during the cycling of all new marine aquariums and on an ongoing basis in fish-only or soft corals systems.

[Note: When using Coralline Gro, only use other supplements containing the elements Potassium or Iron (such as Red Sea’s Coral Colors B & C supplements) according to a measured uptake of each element. Coralline Gro should not be used in conjunction with Red Sea’s Reef Foundation ABC+]


Ensure that the alkalinity is at optimal values and run the aquarium for 4 days at a stable salinity (compensate for evaporation daily) without adding any supplements. At the endof the 4 days test the alkalinity and calculate the “4 day dosage” to replenish back to theoptimal levels. Add the “4 day dosage” to the system. Divide this “4 day dosage” by 4 and use as the daily dosage for the next week.

After a week of adding the daily dosage, test the alkalinity and calculate the adjusting dosage of each supplement to replenish back to the optimal levels.

  • If the adjusting dosage is significantly different from the previous daily dosage amend (increase/decrease) the daily dosage as appropriate.
  • If the measured level is above the optimal level wait for the excess to be depleted before restarting the daily supplementation with the amended daily dosage.

Continue testing alkalinity every week and make adjustments to the daily dosages as
required. If you miss one or more days of supplementing add the complete amount that you have missed but do not exceed the maximum recommended daily increase.
