Pool Size
When I opened my pool at the beginning of the season, I had an algae problem which might have been mustard algae? I wasn't sure and just treated it that way with directions from this site. The water cleared up and the pool has been running clear all summer (Thanks TFP!). Now that I'm getting ready to close my pool for the winter (I'm in NJ), I'm wondering if there could still be algae residue on the underside of my safety cover that could re-contaminate the pool. Should I clean the safety cover before closing? If so, would a color safe bleach and water solution work?

If you have any visible bad areas, it wouldn’t hurt to clean them. But even so, the cover dipping into the water at slam level as it goes on will clean it plenty fine.
