Aquarium Iodine Solution for Advanced Reef Dosing and Coral Dips, Concentrated 50,000 ppm Formula

This aquarium iodine solution gives advanced reef keepers a measured way to supplement iodine or prepare a separate coral dip. The concentrated Lugol’s formula is intended only for experienced aquarists who can test iodine accurately and calculate additions for their individual reef system.

Iodine is used by fish, crustaceans, macroalgae, kelp, corals, clams, and related reef life. Because it can be depleted through biological activity, protein skimming, activated carbon, and specialty resins, regular testing allows dosing to follow the aquarium’s actual uptake rather than guesswork.

Key Features

• Two practical reef uses: dose iodine in the aquarium or prepare a coral dip from aquarium water, giving experienced keepers one formula for two established care routines.
• The supplied aquarium calculation uses tank capacity and the desired ppm increase, making it possible to determine a measured addition after testing the water.
• One milliliter equals approximately 20 drops, supporting small, carefully calculated additions when the bottle label confirms the stated strength.
• For coral dipping, the instructions provide a label-based calculation and a 10–12 minute soak time, so the mixture can be matched to the concentration printed on the bottle.
• The formula contains purified water, potassium iodide, and iodine. Its guaranteed analysis lists iodine at a minimum of 50,000 ppm.
