Hello, I have been lurking and reading as much as I can on this site over the past week. Long story short, my mother in law's pool was an awful swamp. Before coming here, I didnt know better and we used an algaecide.. Didnt work, and now I know why! I do not have a test kit above the strips, so I have been taking water every day to leslies to get tested.
Sunday morning, the test showed FC up to 16, CYA 20. Everything else good according to the pool chem page.
Monday afternoon- FC 6, CYA 30
Tuesday Morning- FC 5 CYA 45.
I just cant seem to keep the chlorine up! The pool is 23000 gals and I have been using the pool calculator. I was shocked that it was so low on monday. Per the calculator, we added 242 oz of bleach monday afternoon and another 121 monday. The FC should have been no less than 12. Tuesday morning added another 121 oz of bleach, waited 30 minutes then collected water to test and the FC was only 6!
It is getting more blue, but I cant keep the chlorine up at all. Keep adding more bleach? Should I go add like 242 oz each hour? We are using home depo germicidal bleach, and Ive read here that others have used it successfully.
