I am running out of my current bucket of IO, and was considering switching to RC almost the same price as IO so I fidure why not, right now I have nothing in my tank but fish, LR, and a Pistol shrimp, I just figured if I was buying a bucket why not get RC, I do want to get corals in a few months, and I also figured that some extra Calcium might help the coraline along. I know you should not really switch salt brands, but I assume IO, is the same as RC, just with extra Calcium etc...., so it would be safe to switch right? So what do you think? Switch to RC, or keep IO?
