OK guys. I don't want to offend anyone with this. I don't want to sound mean. But for the love of Pete, all I wanted to know in my initial post was if:
1. An airstone run overnight would help the morning oxygen levels
2. If that would lessen the efficiency of the CO2 reactor while the airstone is on
You aren't goign to change my mind on temperature or stocking, and I'm not going to chagne yours. And since I can't lower the temperature of the tank, that's a moot point.
1) Yes. It will help for the short term but it does not fix the problem.
2) Yes. it will lessen the efficiency of the CO2 reactor.
There your questions have been answered.
