I’m not sure of the model number of my AquaPro, but I’ve replaced the timer and the wiring harness in it. It worked very well last year, but this year the top plate is not spinning and the bottom one is. I will tear into it later, as I’m just way too far behind on other tasks right now. Fortunately I’ve got a lot of GSH in the pond, that are keeping the YP and SMB busy.
Just an FYI, I’ve called the guys at AquaPro several times over the years. They’ve been very helpful and have sent in the timer and wiring harness at no charge. I’ve got all the leaks plugged. If it would have started up and run well this year (like last year) I was going to call it a bargain. Now I’m back to where I wish I would have spent the extra $$ for the TX Hunter.

9 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these.
I think that's about all I should put in my little pond.
