I agree too. I can't scientifically prove my point, but I switched salt mixes and haven't had a problem since. It is my "guess" that a certain brand did not go well with my well water (before I used RO

Flake, great props for using as a last resort. I prefer the natural way and have not had to resort to chemical solutions. I did, reduce feeding (being new at the time, I didn't want my critters to starve...lol). I know a little better now...
