My LFS won't even sell me IO In all fairness, I think if you've got a good handle on dosing or (successfully) run a Ca reactor, IO is fine. I couldn't use it without upping values for new water, but lots of people do raise values and do all this mucking around. For me, peace of mind is worth the 6 bucks more a week I pay for my salt..but like you said, for me to replace my SPS collection would cost me 10k, so I'm just not interested in skimping on salt.
