Need help with anemone

My green bubble tip is not looking so hot today. It appears that he's expelling his stomach. Everything else in the tank looks ok

My parameters (using Red Sea kits) are
Temp 79
Salinity 1.026
Ammonia 0
Nitrite 0
Nitrate looks like 10
Ph looks like 7.6
Kh 5 - 6
Meq 1.8 - 2.1

The color changed from blue to yellow between drops five and 6
