When I had my first tank roughly 15 years ago I used Instant Ocean. It seemed to be what everyone was using. Today there are a few more options, some of which I never heard of until I just googled (who the heck is Fritz?), all increasingly more expensive than Instant Ocean. BSR is really pushing Tropic Marin Pro Reef Salt. Have people used a few different brands and what did you settle on? I picked Red Sea Coral Pro - but no real reason. Just picked it because a step above Instant Ocean. I'm going to start a survey of the big names to see what everyone is using. Just wondering if this Tropic Marin is actually worth the extra money.
