To run the pump is about $400 for 6 months. I've tried to put the
pump on a timer but during hot weather the water doesn't like it and
turns green.

I wonder if adding ozone to the water would allow you to run the
pump less?

I know nothing about these units but they look promising.

I'm afraid to cycle the pump more than once every three
hours or so as this shortens the starting switch life expectancy.

We had our pool pump on a daily timer for about a decade.
The motor was perfectly fine throughout that time.
