Does RC mean reefcentral.com? I looked for some salt articles but didn't find any. Can you post a link?
I was considering this salt, but since my tank set-up is several months away, I still have time to research. All these studies...some make some brands look good and the next study makes that brand look bad...so I'll do all the reading I can! One study made IO look not-so-good, and in another study, it seemed to be the closest thing to natural saltwater!
It almost makes you want to get fresh seawater or ocean water somehow!
