Maybe your salt is exposed to moisture and the precipitate isn't dissolving

I was using IO until I read an article in RK magazine that tested several salt brands and found IO to be very high in the heavy metals, hundreds and thousands of times higher than NSW.

cant trust everything you read. you never know who's paying this magazine to write this article.

there are many people that use IO and even if these heavy metals do exist, they dont seem to harm anything in the tank

I'm pretty sure Coral magazine wouldn't publish that unless there was some evidence to support the claim. People get sewed for stuff like that. Publications do tend to be somewhat more reliable than forums because they are accountable for everything they print and there is more at steak.

However, I do agree with you. You shouldn't believe it just because one study claims it to be true and if it was crashing tanks the word would get out. I think IO is a perfectly good salt choice.

50 million elvis cans can't be wrong....and neither can IO users.
