" Any reason for running low mg's with sps? "

Only that many of the top sps people in the U.S. do. You don't have to run ozone to keep sps corals.

Most sps feedback has been pleanty of the results wanted doing the low mg and short daily period.

But, this is from what I've READ. I'm just going to start it in the next week or so.

Captexas---yep. Keeps it sparkly clean and clear.
