IO keeps my calcium at around 450.
I was thinking of switching salt b/c I'm tired of having to bump up the Ca
in IO before use, but decided not to b/c of my SPS
and anemones. I'm just curious Fluff, what do you dose? What brand test kit? IO has always tested at or around 350ppm Ca
Edit-Sorry if I'm hijacking the thread Brenden. I don't think switching salts at this time in your tanks life would be too big a deal. If you did I would recommend small PWC
's(5-10%) two or three times a week w/ the new salt mix for a few weeks.
