So i just read the ich thread and ive been doing the doses of salt every 12 hours. but i just have a couple questions. Should i be doing water changes before the new dose? It just seems like alot of salt to be in there since the salt does not end up evaporating. Also it say that u have to do the treatment for 7-10 days. Does that mean that every 12 hours in the 7-10 days do the dose?
