Before you get to thinking lol, no I do not use it. I only use Kosher salt to treat certain things as needed. I was at a buddy's house and he has a 55 gallon African tank. Mainly yellow labs. Anyway..
He was using the salt, I don't say anything as he's been doing his thing for years so it is what it is IMO
But he asked me to grab a cup and BAM! Filled it with water and it got super heated and melted the plastic cup!! This is added to an aquarium with live fish?! This stuff is crazy! I'm calling Seachem tomorrow just to find out what happen.
I see there's magnesium in it, so I know magnesium and water don't mix but... It was crazy. My hand actually got really hot. He laughed as I'm guessing he knew what was coming.
Well... That's it.
