I did a little research after some comments I read in this forum, I think. It seems air pumps and stones do next to nothing to increase oxygen levels in the water.
I got one because the water temp once reached 85 degrees F. in my tank and I know these Bluegill critters live in somewhat colder water. It is a fact that there is less dissolved oxygen in warmer water than in cooler water.
It seems that the factors that affect oxygen levels in the water are surface area, air movement over the water (as opposed to tight fitting tops) and water movement by filter pumps.
Once in a while I see a fish hanging out in the bubble sheet, but not too often.
So, should I leave the pump and bubbles going?
