i just noticed the fish in my 10 gallon tank have ich.i read dave's article and i was just wondering....it says you can use table salt? does this mean grab some morton's salt and mix it with some of the tank water and put it in?? morton's salt? lol geeze i hope so because i just added 2 teaspoons full for my first application, it felt odd doing so, so i thought i would ask before i added my second dose an hour from now.Also, i have a dwarf blue gourami in there with no visible ich atm, is he ok in there with all of these water changes and such? im dont know how sensitive a dwarf gourami is to salt and other things.And one more thing, i dont have a tank heater.....the temp stays where it should w/o one, can i still fight ich w/o it, or do i need to go and purchase one and raise the temp? temp stays at 80-84 degrees F
