| Isn't Reef Crystals just basic IO with a dechlorinator added? I thought I had read that somewhere...
Anyway, I've been using Coralife salt since I started my tank about a year ago, primarily because it was the one the LFS sells in 200 gallon buckets. I've since discovered that Coralife has high levels of silicates (and I'm battling diatoms) so I plan on switching over to IO once I'm through this bucket (got about a bag-and-a-half to go).
It looks like IO is pretty much winning this poll hands down.
