Sps help

[michael Jack]

can someone tell me why my sps polyps are not opening
cal-500
alk-8.5
mag-1200

Phosphate, nitrate levels? Any fish and what type in the system?

 

[pecan2phat]

Calcium and alkalinty is out of balance, magnesium should be higher.

I agree with Warren but this could be multi problem. All corals or only some, fish nipping and so on....With ur alk you should be at 400-430 ppm , mg-1400 range
