This is not my first rodeo in reefing, although my first time trying SPS. Currently running a 36 gallon bow front. A tidal 110 filter, hyggar gyre, 2 power heads and a Smat Farm G5. Inhabitants include a pair of clowns, a Copper banded butterfly (eats frozen mixture from my LFS). About 1.5 inches sand bed, and about 30lbs rock. Just switched from well water to RODI and experiencing a few issues. With my current corals not opening. Any advice would help. Thanks TS
