Any advice on cooling my 6 ft deep inground pool. Texas heat is warming it up like a bathtub. I have a fountain on the tanning ledge. I run the pump 10 hrs during the day. Thinking of switching it on overnight instead and running the fountain. I have also read the fountains you hook up to our returns work. (the evaporation cooling method). Any advice would be great. Spent much $$$ on the pool and would like it to be refreshing and not a crock pot.
