I got home last night, and pool looks really good! Woot, woot! No green algae, chlorine seems to be at 12 based on dilution test. Do I need to get back to shock level, i.e. 15 or just leave it alone??
Also, I think there is some dead algae in the pool...looks like whitish dust. Do I need to vacuum? Will my Dolphin robotic cleaner get it up? Can I just leave it in there? Weather has cooled down so I won't likely swim for a week or 2 so am happy to avoid the vacuum.
My new K2006 test is scheduled to arrive today.
Thanks to all of you again for all your help.
