Whoa holy cloudy water batman

Exposing it for that time wouldn't hurt it.

Your calcium is really high, are you dosing calcium? What salt are you using?

Now I can tell you the white cloud is likely precipitated calcium. Water can only hold so much, then it turns into a solid, which would appear white which sounds like what you are describing.

But your Ph is in line, so that is good.

I would go get a different brand of salt right away, mix it heat it aerate it, and transfer your animals right away.
