Just like what they said that should take care of. Loaches def. dont handle it well but if you can get it quick enough you might be good. I had alot of problems with ich when I had loaches they catch it from being to stressed. Alot of scaless fish have the same problem, not all but alot. yah make sure it says aquarium salt becuase there is a difference. Other then that what they have told you is the best way to go , I dont reccommend using any other liquid treatments from lfs b/c alot of them dont handel well if you have scaless fish or invertabrates esp. The blue med, you have to cut dosages in half and it doesnt work well with them.
