Waterbox Marine 65, Trying SPS

[jeepreefer1]

My tank is a waterbox 65, Algea scrubber, skimmer, two AI Prime 16HD's, two AI Nero 3's. I am currently trying to keep Acropora alive. My Alk is steady at 8.1dkh, Calcium at 450, Mag at 1390, Phosphates 0.10, Nitrate at 10. I have had some Acros in for 7 weeks now, little to no polyp extension and skin is dark green/grey. I have a green slimer with some polyp extension. Walt Disney does not look too good, very little polyp extension and turned brown. I sent off an ICP too Triton and waiting on results. Fish, I have a purple tang, yellow coris wrasse, melanaris wrasse, orchid dotty back, and springier damsel. Any advice is welcome.
