Tropic Marin K+ Elements 1000ml

Tropic Marin K+ Elements 1000 ml — a high-purity liquid trace-element supplement designed for reef aquariums. It delivers essential cationic minerals such as strontium, barium, iron, manganese, copper, zinc, nickel, chromium, cobalt, and boron — all of which corals and invertebrates need for skeletal growth and vibrant coloration. When used together with Tropic Marin A-Elements, it provides a full trace-element profile in just two solutions. Ideal for manual dosing or dosing pumps, it supports long-term coral health, prevents colour loss due to deficiencies, and helps maintain a stable, well-balanced reef environment.
