We purchased a home almost a year and I haven't had to do too much (acid / shock etc) and it's being going fine... considering I haven't had any experience at all.
I did have to contend with a dirty pool, which thankfully turned out to be that the filter needed a backwash. I was so happy!
Now in Phoenix the weather has been horrendous (115o heat) so the guys at Leslies are saying other people are having issues.
Anyways everything has been going fine until I had to shock the pool. And it's been cloudy since... well at least the deep end is.
I have my chemicals balanced. I have backwashed my filter again because the PSI was at 28, now it's 14-16.
I have used Leslie's suggestion of Ultra Brite and that helped but while the shallow end looks clear, the deep end doesn't. I can't see my drain as clear as I would normally see it.
The previous owners did not specify what if any work has been done to the filter so I'm leaning towards that. Is there anything I can do before I have to replace my sand?
