Only ran it for about 6 hours but during the heat of the day here in Texas, with turnover probably already going on. I see now why this happened. I've been sick to my stomach all day. Big clean up this afternoon in store for me.
Will start slow with 15 minutes a day moving forward. I did run it for an hour the day before with no issues, so I moved to 6 hours the next day. I know now that was a poor decision and have this terrible incident as a grim reminder for anyone else that might see this thread when starting up an aeration for the first time.
Most things you read on the web talk only about adding aeration and the huge benefit, but few places get into the proper way to introduce the system. Thank you all for your input. I'll be back with more on this thread as things evolve if you are interested to hear.
