Formel Preis Korall is designed for use in all coral, Malawi and Tanganyika Lake aquariums. Formel Preis Korall delivers, on a calcium basis, the necessary carbon hardness regularly required by invertebrates and coral. The product eliminates excessive concentrations of trace elements and adds vital minerals. Protein skimming is improved.Dosage in Seawater: 20 ml of Formel Preis Korall per 100 l of water once weekly. In case of very low carbon hardness values in the source (tap) water or when using reverse-osmosis water, it is recommended that the dosage be doubled. Carbon hardness in seawater should not be allowed to fall below 8 degrees. Alkaline freshwater, Malawi or Tanganyika Lake: Such freshwater, low in nutrients, should have a minimum carbon hardness value of 12 degrees. Excessively high concentrations of nutrients are reduced and the deficient carbon hardness corrected.
Dosage in freshwater: same as with seawater. In case of very low carbon hardness values in the source (tap) water or when using reverse-osmosis water, it is recommended that Formel Preis Korall be added daily until a carbon hardness value of 12 degrees is reached. Thereafter apply weekly as indicated above.
