Bubble Coral Help

[kbocker]

Hey everyone, we’ve had this bubble coral for 2 years. It’s been doing amazing and quadrupled in size and split once. Over the past two weeks I noticed a large clear bubble in the center. Occasionally it would twist and deflate but would always puff back up to normal.

Today I noticed its mouth open with pieces of the septa sticking out and looking pretty stressed.

Flow is low and indirect
Lighting is 150 PAR
Magnesium 1370
Calcium 470
Alkalinity 3.0 meq/L
Nitrates 0-5
Phosphates 0.05

I dose amino acids and reef chili 2x weekly, phyto 2x weekly, and feed meaty foods like brine once weekly.

Everyone else in the tank is doing well. Please help
