Yes it's true that too much protein can be the cause (Basically it means too much nitrogen).
Just test for NO2, NO3 and NH3 - High level of any of these substance can cause foam/bubble like in the water surface.
But since you are also using chemicals/medicine in your pond, this can also be the reason.
