WTF IS WITH REEF CRYSTALS SALT!!

[ScubaSteve]

I got a batch of RC a month or two ago and have just recently started using it. I've maybe done 3 WC with the new batch. Ever since making the switch things haven't been right in the tank. I've had a couple SPS colonies crap out and I've been having weird cyano and algae outbreaks that I've never seem before. Nothing else has changed except for the salt. I was wondering this weekend if there was something up with the salt, especially after the last WC and there was a weird sediment left behind the in the mixing bucket.

That's weird my last bucket left sediment as well. Like a hard white almost calcium substance. This new one is fine so far, still haven't checked the batch though.

maybe i missed it but have you tested the new batch of salt by its self to see whats causing this or if anything is off??
