Report: New (2-speed) pump installed Thursday. I added a gallon of bleach to the water on the pool cover that evening, and took the cover off Friday after work, started the pump, drained water down to skimmer level, and fired in the chlorine and the Kreepy Krawly. The pool is almost completely clear this morning (except for some needles that the KK didn't get to yet). The winter cover is a little slimey in places, so I may need to wash it off with some bleach and water (and/or a gallon of that cheap foamy algaecide) before storing it.
