Brightwell Aquatics Lugol's Solution Iodine Supplement

Brightwell Aquatics Lugol's Solution is concentrated iodine (I₂ in potassium iodide) for reef aquariums where iodine is consumed by corals, clams, and crustaceans faster than water changes can replenish it. Iodine plays a direct role in the molting process for all crustaceans and in coral pigmentation and tissue health. It depletes quickly in a well-stocked reef. Dose with caution — iodine toxicity is real and the margin between therapeutic and damaging concentrations is narrower than most supplements. Always verify with a reliable iodine test kit and dose incrementally.
