ive have utfse, but i havent found anything pertaining to my question on iodine. i usually use a 2%tincture of iodine from my neighborhood pharmacy for my crystals, but i was in my local feed store and noticed 1% tincture at a fraction of the cost of the pharmacy. im sure anything under 5% will work, but the bottle says "gentle iodine". what the hell does that mean? active ingrediant is 1% titratable iodine. am i correct to think this will give me what i need? i really hate throwing away a lot of time, energy, and product! please steer me in the right direction!!
