Haven't checked in for a while as pool has been sparkly and clean.. Went on vacation last week and came back to yellow algae on walls in shaded end. There's been a ton of rain here too so that's compounded the problem, I'm sure. Do I need to slam? Is it possible it'd go away without doing that? My numbers:
I turned the SWG up to 70% from 50. Thanks as usual for any help.
