Are you running 400W 20K's? I agree that 20ppm is a bit on the high side for SPS, are you getting any polyp extension or is it closed up 100% of the time. Have you checked for parasites? Also have you checked PO4? If PO4 is high, I find deepwaters tend to brown out easily. It looks like maybe a loripes or a granulosa, which should have the white base with purple tips.
