Was using RC for quite a while, but got kinda tired of many hours required to get salt to mix cleanly without cloudiness.
Recently switched to HW Marine salt and really like how fast it mixes together and it matches my parameters nicely. Would consider switching back to a "cheaper" salt. Running mostly LPS with a handful of SPS, I don't think the LPS are too particular on salts, For me, the cheaper salts just tend to be lower on magnesium than what I would prefer to run at (+1350 ppm).
My main motivation for starting with RC was due to it being the salt by LFS uses. I liked knowing if I had an emergency and needed to do a large water change, I could rely on LFS saltwater in a pinch.
