wheebz said:yep thats about right
iodophor also has phosphoric acid added to it as well
Yep, my understanding is that it's the release of free iodine that actually does the sanitizing. I got a copy of the MSDS for Iodophor and it only lists 2 ingredients considered hazardous, Iodine and Hydriodic Acid, which is an aqueous solution made up of Hydrogen Iodide and water. Seems to me that in a pinch you could use a bottle of Provodine Iodine to sanitize.
The dilution of 10% Provodine Iodine would be 1.25 ml / l which converts to .16 oz / gal. Might want to check me on this though.
