thought this was interesting, maybe others will to; the fish are slow and more or less still now as temps outside are at or below freezing. I noticed the other day, single individual bubbles rising (not the open tube from the aerator in the back). This is O2 produced by the algae on the pond walls and esp, bottom. I notice this in the summer but with the fish being so active, didn't really pin it down to algae release. Without such activity, the bubbles are more prominent. And this day, the sun was shining, which seemed to increase the quantity of bubbles relative to a normal cloudy day here in Mi. Anyway, a quick vid to illustrate (easier to see if full screen).
