Answer
Hello Stephen!
I am not entirely sure if you mean to put pea gravel in the bottom of the pond filter or the bottom of the pond.
Either way, I am not a big fan of it.
Gravel in ponds, no matter where you put it, is notoriously hard to keep clean, encourages bad bacteria, prevents you from vacuuming, can clog and damage the pump, etc etc
