Frogspawn bouncing?

[gavinisdabomb1]

This particular frogspawn hasnt been doing great recently. I suspect it was due to a change in flow and a drop in phosphates at around the same time. Ran out of phos reagent but PO4 dropped about 0.3-0.4 after raising dosing AOR to raise alk and has been doing better. But i got home today and the flesh-band is bouncing? What does this mean?
Alk:8.3

ive seen this when a euphyllia has a receding of its tissue band, and when recovering the tissue band swells up a bit and re-covers the skeleton.

I’d watch it closely, it should get more flat and regain its flesh band slowly.

Also I hate how we call this “bouncing” now
