CORAL SYSTEM 4 – 1000ml – Halogen Supplement for Coral Color, UV Protection, and Structural Support
CORAL SYSTEM 4 – 1000ml is the final component of the Korallenzucht Coral System 1-4, designed to provide a targeted supply of halogen trace elements essential for enhancing coral coloration, structural development, and biological resilience. Suitable for reef tanks not using the ZEOvit® method, this formula supports natural pigmentation, UV resistance, and metabolic strength.
Containing purified water enriched with potassium (K), fluoride (F), bromine (Br), and iodine (I), Coral System 4 promotes red, purple, and blue hues, improves coral skeletal formation, and strengthens coral tissue against oxidative stress. Iodine and bromine play key roles in pigment synthesis and immune defense, while potassium and fluoride contribute to overall cellular function and skeletal matrix development.
Coral System 4 does not include calcium, carbonate, or magnesium, which should be monitored and supplemented separately. It is 100% reef safe, compatible with automated dosing systems, and suitable for both nano and large reef aquariums.
