CORAL SYSTEM 4 – 250ml – Halogen Trace Element Supplement for Coral Color, Structure, and Health
CORAL SYSTEM 4 – 250ml is the final component in the Korallenzucht Coral System 1-4, a complete nutrient program designed for reef tanks that do not follow the ZEOvit® method. This supplement delivers key halogen elements that are essential for coral pigmentation, UV protection, tissue strength, and overall biological balance in marine aquariums.
Formulated with purified water, Coral System 4 contains potassium (K), fluoride (F), bromine (Br), and iodine (I). These elements are vital for cellular metabolism, photosynthetic efficiency, color expression, and skeletal development. Iodine and bromine help corals resist UV damage and enhance invertebrate exoskeleton formation. Potassium boosts red and purple coloration, especially in SPS species, while fluoride supports skeletal tissue formation.
Coral System 4 contains no calcium, magnesium, or carbonate, which should be monitored and dosed separately. It is reef safe, compatible with manual or automated dosing systems, and suited for nano tanks or large reef aquariums alike.
