We just installed two 2'20' solar panels and 8110 intex swg. When I talked to the girl about the run time for the swg she said I should only have to run it 3-4 hrs per day, however the manual says that for the size of pool I have 13500k I should run it 9-10 hrs per day. If any one can help or has a intex like mine with the same size pool I would greatly appricate it. Thanks a lot!
