Ok, I've read the post from 5 years ago about building some jets to cool the pool. That is exactly what I was planning to do, unfortunately for me, my return lines are 2" (or less but not 1-1/2") MALE. Does anyone have this type of set-up and can it be done? I really don't want to purchase a chiller if I can save myself 2k! Temp is averaging 91 so far in June/July. I'd love to get it down to 85 at least.
