I have a Pentair Clean & Clear Plus 320 filter which worked fine until we had a freeze (13 degrees) last winter. I suspected the cartridges may have been damaged so I replaced them but it still appears that something is wrong. I kust returned from a trip and found the pool water itself to be clear but lots of what appears to be dead algae on the bottom. When I vacumn it up I can see dirty water coming back out through the return lines. I have checked the bottom mamifold and the top assembly and can not find any cracks or breaks.
I do not want to continue replacing parts that may not need to be replaced.
Any ideas?????
