This has been a nasty opening so far. Mice chewed through my cover, which mean I could not get nasty water off of the cover, and much of the leaf matter got into the pool, despite my leaf net (which otherwise worked beautifully, except for small leaf particles. Pool turned green, added a buttload of chlorine. Had a terrible time putting the pump basket together, drain plug broke off. Accidentally cut pump basket trying to get it out. Dumb. Then while assembling the pump, the ball valve o-ring had kinked, which led to bubbles in returns and the pump losing prime over night. So I used the "hose method" of suction side leak detection, (which worked awesomely btw!!!!), found it, replaced it. Left my pump running all night and work up to it about 3-4 over the "red line" psi this morning, but the pool was at last crystal clear (mostly).
So it's getting there and I'm learning. Too cold to swim anyway so I really didn't mind that much.
