This is only the third year I've had a pool (it's a rental house) and the first that I'm opening it myself. I've been working on my pool for two weeks. It is an above ground 27' x 4' round pool. I have a Hayward sand filter.

I started out with a dark green pool. It is now light green and cloudy. I was working with a pool company but they can't seem to give me advice to get my pool up and running. I used yellow-out, granular 56 and flox per their instruction. While it got me to the light green stage I've been battling the PH and Alkalinity trying to get them balanced. The pool company told me to get them in balance before adding chlorine. I'm lost.

I have company coming in two weeks and was hoping to have my pool ready by then. Please, please help.
