Instant Ocean Reef Crystals crashed my Tank!

[Samw]

I've thrown bags of Instant Ocean out before as well. It wasn't worth trying to prove the salt was bad to the retailer or manufacturer so I just buy a new bag and generally the new bag is fine. I haven't had fish die but the salt is inconsistent and at times it doesn't dissolve completely, the water is brownish or cloudy, and sometimes ****es off the corals especially sensitive SPS. If fish are dying though but no one else is having that problem, there might be something more to it like something in the bucket or something was tampered with.
