Dave (or anyone ), I want to give this a try.

Potential problem is, my pool only has one return, so I would need to aerate my entire flow. What would you suggest for this approach so I don't constrict my pump?

I was thinking of calculating how many 1/8" holes would fit into a 1 1/2" pipe, taking a straight seciton of pvc about 8' out of the return (half the width of my pool), then a 90* elbow turning it towards the deep end (32' length), a 2' section of pvc with a capped bushing taking it to 3" (if possible) and drilling the required number of small holes into the cap, in effect making a big shower head. This I would angle up to the sky to get the best affect, and only operate it at night when it's not windy

What do you think?
