The GROTECH ABC-system could be easily dosed by automatic dosing pumps.
The GROTECH ABC-system does not cover the complete requirement of quantity elements such as magnesium, calcium and carbonates.
These values must be checked regularly and, if necessary, compensated by adding GROTECH Magnesium pro, Calcium pro and Carbonate pro or products of the GROTECH Element series.
Corall B contains magnesium, iron, chrome, manganese, nickel, cobalt and copper.
Dosage: Max. 10 ml per week for 100 l aquarium water.
Dosage quantity refers to a well populated coral reef tank.
In order to avoid fluctuations in the concentration of trace elements, a daily or better several times daily dosage is recommended.
Do not mix Corall A, B, C and VitAmino M in the measuring cup but add them separately to the aquarium.
Rarely does the colour intensity of hard corals does decrease after colour successes. If this effect occurs, we recommend reducing the dosage to 30% of the last used quantity.
As soon as the colours return, gradually increase the dosage again until the optimum quantity for your aquarium has been found.
