Well, I got in and plugged off the hoses so I could change out the filter and install the new inline chlorine feeder (hopefully this one will work.) Brushed up all the algae, the bottom, and the sides until the whole pool looked cloudy again. There really wasn't much debris settled on the bottom, so I didn't bother with the hose/vacuum thing. Then I turned the pump back on and shocked the pool again. Hopefully it will look better tomorrow.
