I am using the TFP method, and things are looking great. However, I have a leak somewhere. I am losing about 2 inches of water/week. I also have some air bubbles coming from one of my returns. Additionally, I went to turn the Polaris cleaner on this morning, the pump comes on but the cleaner does not move. Any help would be appreciated. I considered calling a local pool company to come take a look, but thought I would try here first. Any help is appreciated. Thanks.
