Pressure washed cover and pool deck. 1 hour am, 2 hours pm. Cover ropes are filthy black in any areas that have been on tracks. A black grime gradually came off the cover and tracks, but had to be waged and directed to the cover pump immediately OR the black grime would immediately resettle (on cover) . Jim thinks it is the aluminum. Could be. Inreading about saltwater pools and automatic covers, they say that salt damages aluminum, but not stainless steel.

Pool cover would not close completely, despite multiple attempts. Stuck at 2” open, 1! Open, then 2’ open. Jim added knots to both pool ropes, moving more excess rope to outside of rope reels. First added knots at about 6” from end, resulted in no change to cover position. Then added knots at about 12” from rope ends, and stuffed the loose ends to the inside of the rope reels, tucked under the working sections of ropes. Pool cover closed completely.
Approximate day and time, Chlorine tested 5? Turned on SWCG and set to 40%
I THINK what I added was Calcium Hardness Increaser, Sprinkled over deep end of pool. However, Diane was here and we were talking so I might have gotten confused and sprinkled Chlorine Stabilizer instead, which us supposed to be dangled in a sock and pump left on for 24 hours, which I do not think happened.
