I am sorry to hear about the bad news. Here is take home message, in my opinion.

Diffused air systems are not all they are hyped up to be. Many of my clients have had fish kills even with diffused air systems in place. Many have killed their fish by creating turn-over. Once you get these systems going, don't use a timer, run em 24/7 through the growing season.

Pond more than 10' deep? Run a surface aerator in addition to the diffused air system.

Pond less than 10' deep? Run a good surface aerator and forget about diffused air.

Nothing can take the place of a good surface aerator. If you have lots of pondweeds then stay away from units with a bottom screen that may get clogged up and require lots of maintenance.

This advise is for Tracy direct: Get yourself a 2HP paddlewheel from AES for $1321 and be done with it for good:

Get an extra replacement motor just in case, so you'll have it when you need it.

Those don't come with power cable, so you need to supply that yourself. You will be off the races, and hopefully won't have to worry about this happening again.

It sure is frustrating to watch as an industry steers pond owners towards towards ineffective, high maintenance, and expensive products, while there are more efficient and effective solutions hidden in plain sight.
