I have two 55g tanks and add salt and stress coat with my water change every week. Are they needed? I only add 10ml of SC and 3 Tablespoons of salt. They call for way more but i think thats just to get you to buy more. I understand salt helps heal, and stress coat helps slime but is it needed?? I have well water and never add cond because it is not needed my water is good. Never have problems just don't want to add stuff that is not needed. Fish are african cichlids in one, and comm in the other.
