Its finally here! Red Sea Reefer G2+ 750. The RO unit is from Bulk Reef Supply, 6 Stage Deluxe Plus 150 GPD Water Saver. A little rock work. Took two days to fill, off and on with life getting in the way. I mixed in the salt with everything empty, the reefwav45 at the bottom and set to max made short work of mixing. I then drained out some water to put in the sand and rock then refilled. Took about 18hrs to clear back up. The rock was cured in a brute for about two months. The wiring is still a work in progress. Only one issue. One of the reefwave45s was seized and part of its ceramic shaft was broken. I contacted Red Sea and a replacement motor is inbound.
