Hole in my frogspawn?

[waitwut]

Yesterday I increased the flow in my tank by adding a Maxspect Gyre 330 as I was having issues with detritus building up on the sand and with cyanobacteria in a few low flow areas. I'm running it on a low setting (no higher than +/- 30% power) and most corals seem fine with it but today my frogspawn has less extension than usual and I noticed what looks like a hole or a tear in the flesh between the polyps.

Anything I should be concerned about? Could this be related to the higher flow?
