Couple of things. to clear the algae you need to shock the pool with a high concentration of chlorine and the turbitity is simply floating particulate. Alum will coagulate it and get it to the filter. backwash every day.
nothing like a good scrubbing with a brush to clean the tiles.. at least you can get in the pool and stay cool for that effort. But after shocking it.. dont want your speedo to melt off...
