If the medicine says "2 drops daily" doesn't that mean that in a few days there's going to be a very strong solution of the chemical in the water? I know I must sound stupid, but I'm treating my fish now, and I'm unsure whether to just add medicine to the water-change water, or keep up the full dose. The medicine is Ich Cure, and smells strong. My fishes are tiny. Can I make the dose lighter? And for how many days after the spots are gone? I'd like to know how others have done this, and their results.
