How to Dose Lugol’s Solution
First, test iodine before adding any supplement to ensure accurate dosing. Each ml raises iodine in 1 gallon by 34 ppm (1.7 ppm per drop). Never exceed 1 drop per 35 gallons in a day.
Why Iodine Matters in a Reef Tank
Clams, corals, and different invertebrates rely on iodine for functionality. In the ocean, levels usually remain steady, but in aquariums they can fluctuate and dissapear quickly due to natural uptake and filtration. Brightwell's formula provides both iodide and iodine, which is found in seawater. This allows your reef to get consistent results and balanced supplementation.
