Just a couple of notes to those new to the CaRx, test, wait & test again. I had mine set, running 30 on the pump and for about a week I was stable at 9 dkh in the tank. I let it go for a while, untested (2-3 months) and tested it & I was at 14 dkh. I lost a couple of corals due to the high ALK. I slowly brought it back down to 9 and now my pump is running at 12 (instead of 30). Its been stable for a week, but I plan to keep testing at least once a week for a while.

Second note, there is 7523-60 (no head) on ebay right now for like $300. Great deal. Not mine! FYI
