    Cartridge filter blowing cloudy/dusty water when vacuuming

    I have an inground pool approx. 14000 gallons I think. Pump and filter only been running about 2 weeks. Pentair cartridge clean and clear filter and seem to be blowing cloudy/dusty water when I vacuum pool. Any thoughts. It was clean 2 weeks ago and fairly clean water to start with.

    You are sucking air. It looks cloudy when it comes out of the return. I'm guessing you don't have a good "seal" when vacuming. Is the vacume connection to the skimmer fully attached? The first time I vacumed, the same thing happened to me. Next time when I had it properly connected, I had good suction and the water coming from the return was normal. You may also have a hole in the hose or connections. That's my guess.

    Try adjusting your vacume hose setup and see if you had proper seal/suction.
