i'm using crappy crystal seas because 3 years ago, supposedely it was THE salt. well it sucks. i have stable parameters, but i blame it for several STN episodes w/ SPS. i will be switching this week. i'm either going w/ SeaChem reef salt or IO. probably IO.
- when switching u shouldn't have a problem as long as you do first water change w/ 1/2 and 1/2, then maybe like 3/4 new brand and 1/4 old brand on 2nd change. by 3rd all new brand. this is what i'm planning. Seachem is supposed to be great salt except id does have high boron levels, 4XNSW. wheather or not this will affect corals remains to be seen.
- has anyone been using seachem for a long time? anyone have problems w/ Ca, Mg, Alk levels while using IO? i know of some that mix oceanic w/IO because they say w/ just IO, they need to supplement Ca, Mg and Alk.
