Are my corals dying? Torch splitting and receding + mesenterial filaments

[Matt Bravo]

It can to some degree but if you are trying to sustain LPS corals they prefer dirty water. Nitrates 10 to 15 and phosphate. 05 to .1. Your magnesium is elevated also which may harm inverts. Keep it 1400 to 1500.

I second this, raise nitrates and also make sure there’s no sand of inverts bothering the coral at night. (Always a possible some hermit crab could go rogue and start nipping at the coral)
