I did do something like that with an air pump all day Sunday and Monday. I shut it down when I saw BH at the surface gasping for air and pretty much every other fish in the water dead. If everything is going to die, then those pain in the --- fish need to die too.
I do have thousands of minnows still swimming around the shallows at the top of the water. No idea what species they are, but I do know there are several different species mixed in together.
