Hi Jen, hang in there. It'll clean up long before autumn.

I had a green pool once when I went on vacation for 6 weeks in September and just left it. I had shocked it, put the solar cover on, turned the pump off and drove away. It was still very warm during the days and I expected it to go green. Still, it was a bit of a shock not being able to see the bottom of my 52" AGP when I returned, to see it match color to the surrounding fir trees.

I can't remember how much chlorine it took but I do know that each day there was improvement. Getting it back to clear and sparkling took about 10 days of bleach, brushing, running the pump the entire time, backwashing the filter every other day, changing skimmer socks three times daily . . . it was a process and required frequent attention but it did clear up with just chlorine.

It takes a lot of patience though.
