I have a 60 gallon cube and sump. I run only a skimmer, and filter sock, and do a ten gallon water change each week. That's it. Tank is doing excellent. Codals are looking good and growing. Before I go any further , I know the old adage if it's not broke don't fix it but anyway....i have been looking at the triton method but am not sure as of yet. So if I stay with my current weekly water changes I have thought of switching from red sea coral pro salt to instant ocean. I know I will then have to add cal, alk, and mag to the water when I mix it up. Main reason is I can get a whole year supply of instant ocean for the same price of one bucket of red sea because instant ocean is on sale. What do you guys think? Stay with what I got or make the switch? Thanks for your help.
