1. You can't have too much.
........ I agree
2. A bubbler, a waterfall, etc. does not add air to the water. The churning
of the water breaks the surface tension allowing air to infuse into the
water.
.......... yes, a bubbler does add air directly into the water as the bubble rises in
the water, AND a bubbler helps circulate the water from bottom to top AND bubblers
help blow of the toxic waste gases. LOL.. oxygen can get past the "surface tension"
of water. in calm water the rate of oxygen in = oxygen out at the surface.
diffusion is very slow without "mixing".
3. If your fish are not at the surface gasping like a 2 pack a day smoker.
You probably have plenty of aeration.
......... however, after a night of plants IN the water (like algae) using up all the
oxygen in a pond where the temp has risen over 75-80oF one may not see the fish
gasping and it WILL be the biggest fish die first.

Air bubblers are like self timing water meters.... better safe than sorry. Ingrid
