ok just an update. The pool is a greenish blue and clear. Im running the pump 24/7 and keeping my fc at least 20ppm. I know its a little high for a cya of 35 but ive been fighting this for over a week and i want this cleared up for the 4th. Is it safe to swim at these levels, since i have to go in and vacuum or should i try and vacuum from the outside?

also, how are your feelings of polyquat once the algea is gone? do you use it regularly for maintanance and does it work?

thanks again for all your help
