Lately, after using our Hayward Navigator, the pool water has been cloudy.

Not a green cloudy like if the Nav was travelling too fast and kicking stuff up (it isnt, Ive watched it for a while and made sure the speed isnt too high). The pool just seems to have a "white" cloudiness to it. I dont see any little air bubbles coming out of the returns, nor do I see any dirt (sometimes algae comes back in, but only right after backwashing the filter and I avoid vacuuming right after backwashing the filter).

If I vacuum manually this doesnt happen.

Any ideas?
