I've got a friend that's going to be renting a house with a pool in my neighborhood. The landlord insists that they have a pool service. They have tried to tell the landlord that they can handle the pool themselves, but the landlord has had too many bad renters in the past, and refuses to let them do their own maintenance. I even told them to have the landlord come over and look at my pool , didn't work What do you guys think they can do to maintain a perfect pool like mine? My ideas are 1:buy a TF-100, 2:Read pool school, 3:Remove trichlor tabs from chlorinator and use bleach once CYA is about 50. What do you guys think?
