I would also add, don't be afraid to feed your fish!
LPS in general, euphyllia in particular like a little dirtier water. I keep my LPS/softie tanks at 10-15ppm Nitrates and anywhere under 0.10ppm Phosphates. I feed my fish pretty heavy every day and broadcast feed Reef Chili 3x a week. Between my CuC and the coral uptake, I have issues keeping my nitrates and phosphates up. I actually have to dose Phosphates occasionally.
