We are new to having a pool, so don't have much experience with taking care of one. We seemed to be doing pretty good with it, but then we went out of town and when we returned last Saturday it was green. We were still able to see the bottom though. I'd been using the Taylor 2006 and all levels were good prior to use leaving. When we returned we were at 0 FC. I added a half a bag of SHOCK from Leslie's and started vacuuming away. It was getting less green, but looked cloudy. At that point, our TA was high, so I added acid. The morning after adding the acid things were looking pretty good, but we were still getting a lot of green in the filter and could still see some settled on the bottom along the seams. I tested again and the pH was low (slightly less than 7.0). I had to go to work and didn't have any ash. Anyway, when I got home last night the water was getting greener again. I added 10 or 11 ounces of ash. Then because things were green I added 2 lbs of granulated chlorine. This morning things looked even worse. If I remember correctly, FC was at 20, pH was 7.0. I added another 11 ounces of ash. When I got home tonight FC was 15, CC 0.5, pH 7.2, TA 150, CH 200, and CYA is now at 100. I have no idea what to do. Can someone please help me.
Should I just drain the pool and start over?
Thank you for any input.
