Cloudy Pool after battling algae.

[Jbonnette]

The forum has been beneficial to me so far...only makes sense to support it.

I'll give it a few days for the filter to do it's work. Is there a way to tell if the filter is doing a good enough job? Currently the filter pressure goes from 12 psi to 22 psi in around a day or a day and a half. While backwashing, the water looks pretty dirty and takes around 2 minutes to clear up. It seems normal, but just wanted to make sure.

On the CYA reading, I could not get a reading last night on my kit. But when I went to the pool store the other day, they had a pinpoint testing machine that said it was 9 ppm. I realize that I need to add some CYA. The pool store folks said that while adding I shouldn't backwash for a few days to give flakes a few days to dissolve. Considering that I have to backwash every day or so now because of the algae clean-up, should I just wait on adding CYA? I was thinking that perhaps adding the CYA to a filter sock might allow me to add while still backwashing?

My calcium hardness levels are a bit low. 134 was the pool store test. I didn't bother testing them last night because from what I understand I really don't need to worry about them because I have a liner pool.
