The title says it all. Neglected the pool while not swimming in it this summer, and ran trichlor FAR after I should've stopped. (Pool has a slow intermittent leak; CYA drops over winter as water leaks and is refilled; during season I run mostly trichlor until CYA is around 80; repeat) I also let chlorine levels drop too low on multiple occasions, and ended up with some persistent algae that seems to come back in the same spots a few days after SLAM - I'm thinking mustard? First year I've ever neglected pool, and as a result, first year I've ever had trouble with algae that didn't clear overnight with a SLAM.
Selling my house but I have a conscience, and I'd like to not leave the new owners with mustard for next year... but I don't want to get rid of it at the expense of the pool liner. Thoughts?
