SWIM had a dream that she walked into a pet shoppe and found a rather dense feeling 8oz bottle of liquid --"iodine nutrient" for her itty, bitty fishes. The bottle contains I2 and KI along with purified water and (she forgets, but probably) etOH.. It was around $6.. Last time she checked, this was cheaper than tincture..
SWIM doesn't need I2, so she didn't bother to buy it.. But this may be something...
