Ok, this has me stumped. Readings last night were the best I have seen and I took them a little later in the evening (9pm) but I still expected based on the other readings and my undersized bottom and surface aerator that I would once again have very low DO in the morning. But too my surprise the DO readings this morning seems to be as good as I would hope for based on what I have read here - please correct me if that's the wrong assumption. The readings for last night and this morning are below.
Is it possible that the aerators have finally caught up after running 24/7 for 5 days or is something else at work here? I hope this disaster is over.
It has got me thinking, if I had a properly sized surface aerator would I just run it at night for the entire summer to hopefully eliminate the chance of this happening again?
Seems like a DO probe that could be left in the water 24/7 and provide readings remotely would be a must have item? Does anyone make such a device. Even with my MW600 I don't think I would have noticed the problem until the biggest fish in the pond started floating.

I appreciate all the feedback you guys have provided. I would be completely frustrated without you guys and this forum.
Thanks!
