My pool is 20X32X45 True L. It has 2 depths on the short leg - 3 1/2 & 4 1/2 feet. The long leg then goes to a depth of 8 1/2 feet. By my estimate that is 40 - 45,000 gallons of water.
My questions are:

Anyone use a SWG on a pool that size?

Is there a consumer size that large or do I need to go commercial?
I rather oversize than undersize.

Any downside to using SWG in a liner pool?

thanks all
Frank
