Seems as if most are liking the red sea over rc. so tells us why? It is a full $20 more and less salt. I have been using rc for several years now with pretty good results. My biggest issue is keeping my mg levels up.

I have come to like RSCP over the years mostly due to the size of my tanks and what I keep in them (mostly softies and lps).
RSCP has most of the levels that I need without too much fuss. The only thing I add is a 2 part once or twice a week.
For me it is just more cost effective and easy to maintain.
Which, of course, makes it more enjoyable
