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
