Catalina water which is taken from somewhere off Long Beach, is low in magnesium and calcium. And certainly low in things like boron and other trace elements that coral enjoy. Would use that for FO tanks. Unless you use a CalRx or dose on a doser.
back in the days when i started my tank i used Catalina water, but after a few months i got tired of lugging bottles around and made my own. for the time i used it no problem here.
What the helll do you know? You're a newby with only 94 posts! :tongue (2):
LOL, for those who don't know the inside joke, Dave's been around this hobby even longer then I, which makes us both older than dirt I suppose..
Good to see you sticking it out.
I used Oceans in Motion (Andy) he delivers to stores like The reef in Fullerton, and Jans Tropical. He gets his from a source in San Pedro. Used it for over 5 years. Good stuff, lots of growth with my corals & Non-photosynthetic corals.
