I have put at least 25 pounds of chlorine in my pool still registers no chlorine.I have put in at least $150 for the chemicals and my pool still looks terrible. Please help me get my pool back in working order. I would appreciate this so much.I am changing my filter and cleaning it 3 to 4 times a day. Please help
