My boys made me a pvc aerator. Good news - in 18 hours it dropped the water temp from 95 to 84 and lowered the TA from 210 to 160. And that's with the pump on low. Bad news - the weight seems to be pulling the pool wall inward and I'm afraid the liner will pull away from the jet/washer going thru the wall. I've searched for other diy pics but can't find any that show how they are supported for AGPs. The pics focus more on the shape, holes, and hole sizes. Ideas?
