I'm back. Been a while.
So I have the green problem again. Started in April (Arizona, about 80+ degrees in the pool). The pool chemical guy says it's not algae, but it has now spread. I can brush some off, but I fear there are stains now since it won't come off like it used to. I clean the filter, backwash, vacuum, and now testing religiously again. I have been disabled, so I haven't been able to brush every day or even swim. Every time I tell the service to tell the tech to SLAM/SHOCK the pool he leaves a note "Too much tree in pool, not algae."
A few years ago, the original tech quit, the service didn't send another tech out for a few weeks, and the pool was a swamp. So cloudy green that you couldn't see the second step in the shallow end.
If it's not algae what is it and how do I get rid of it?
I know I forgot a couple, but ph was 7.5 and the other tests were ok from what I can remember. This was before draining to the skimmer level, vacuuming, and scrubbing again. Now filling and will repost levels and ugly pics if necessary. Of the pool, of course!
