I backwash when the pressure increases 10 psi or so which is about once a day. It seems to be clearing until I turn on the SWG, then it foams up again. This was happening even before I replaced the cell. I would say that the foam appears to be lessening each time but it is hard to tell. I thought about air bubbles because the foam dissipates after I turn the SWG off. I found a slight leak in a fitting in the return pipe between the filter and SWG. I will dab some rain/shine glue on it when I can shut the system down for a few hours. It is possible that could be the culprit. I used algaecide late last summer but not this year. We had so much rain last fall and winter that I have pumped out approximately 2 feet of water prior to opening. I continue to add bleach to keep the chlorine up (although my tester only goes up to 5). The pool walls don't feel slimy and the foam doesn't feel soapy. I can detect a slight chlorine smell but not as bad as last weekend. I can only see about 18 inches or so deep into the pool. We did find a turtle and it took 3 days to catch him because of the cloudiness (turned on the lights at night to capture him). I also added a skimmer sock to catch small particulates. I will continue the bleach and 24/7 filtering. Thanks for the welcome and the help.
