GroTech Corall C Trace Elements


Trace element solution for soft, leather and hard corals.


Fluor, Iodine, Boron, and Molybdenum are the elements found in Corall C that are essential to maintain natural colouration, improve polyp appearance and promote healthy coral growth. The vital biological processes in the cells will be fuelled by these compositions which is integral for a functioning organism.

When used in combination, Corall A, B and C contain all the compounds and microelements necessary for corals to successfully maintain and reproduce corals, ensure natural colouration and enhanced growth and also improve polyp appearance. These are essential for the vital biological processes in the cells and promote a functioning and healthy organism.

With additional application of VitAmino M, the vitamin and amino acid requirements are covered in addition to the supply of trace elements.

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.
