My husband rigged up hundreds of feet of black hose to make big solar coils and put them on the roof. Also, we have been using a thick, blue solar blanket for about 2 months (the coils have been working for a few weeks). My pool is only 74 degrees this morning! Temps have only been in the low 70s lately but other people with this set up seem to all say they have 80 degree pools so I am wondering if I am just cursed to freeze all summer...help!
