Tropic Marin® K+ ELEMENTS contains essential cationic trace elements to support an ideal growth and natural colouration of corals.
Trace elements are natural minerals, which are needed by the aquarium inhabitants for active biological processes and especially needed by corals and invertebrates for skeletal growth. In seawater there are tiny quantities of these elements, which are consumed in a short time by coral growth and other processes. Regular supplementation of these trace elements is therefore unavoidable.
