the ratio of KI to I2, 2:1, remains the same, but the percentage os Iodine in solution total can different. pathology labs use a 1% solution instead of a 15% solution, which is what V suggested to me.

Description:

Kent Lugol's Solution provides a strong source of free Iodine and Iodide to reef inhabitants and macroalgae. Although it’s very effective when used with stony corals, systems containing xenia and soft corals are particularly benefited by the use of Lugol’s Solution. Used as a dip for stony and soft or leather corals, Lugol’s will help rid the animals of unwanted parasites and harmful bacteria. This product helps foster improved coloration and prevents bleaching of all corals due to changes in light intensity, and enhances coral polyp expansion. Kent Lugol's Solution provides a key nutrient for marine invertebrates and fishes, and contains no phosphate, nitrate, gluconate, or other sugars.

Directions:

Lugol's Solution is VERY strong, and must not be overdosed! Add 1 drop per 25 gallons aquarium capacity weekly to sump or an area of high water flow. Can also be diluted in one cup of aquarium water and administered directly over xenia colonies or soft corals with rigid tubing or a pipette. Do not mix with other supplements outside the aquarium. To use as a dip for corals, in a separate bucket add 40 drops Lugol's Solution to 1 gallon aquarium water, and immerse coral for 10-15 minutes.

Considerations for use:

Kent Lugol's Solution is a very strong source of iodine, and must be dosed carefully, according to the directions. Lugol's Solution is very useful for xenia, soft and stony corals, and other polyp cnidarians. This product is best applied to an aquarium by adding it to a strong current of water where it can be circulated into the aquarium over a prolonged period of time. Lugol's Solution can also be diluted at a ratio of 1 drop to 4 oz. aquarium water in a separate cup and targeted directly up-current from xenia colonies or soft corals, but take care when using this method (not all corals will react the same; stony corals do not generally appreciate this target method of applying Lugol's).

Ingredients:

de Ionized Water , potassium iodide, and iodine.

Normally just a legal disclaimer.

Its often put on 'Raw Milk' so the producers cant be sued by the Pasturised Milk Cartel.

As long as the concentration is correct, I would imagine purty would be high. People who love their fish wont allow unnecessary crap in their aquariams. You could always phone the company and ask for a full ingredients list if its not on the bottle/internet?
