I drained until I saw some wrinkling starting at the corners, I think I changed out almost a third of the water. I wanted to get a higher percentage changed, but I really want the liner to stay put too.
I did the CYA test with my walmart test kit, I could see the black dot until the test tube over flowed=0 CYA. I used the pool calculator and came up with roughly 40 oz. CYA called for to raise it to 25. I would like to add enough to start holding FC and then start using my left over chlorine sticks to add a little more. I still have about 60 lbs. of the sticks left from before I learned about BBB. Is there a ballpark idea at what rate does using the sticks add CYA to the water?
If the water change wasn't enough, I'll do it again and again..my town utility will waive the sewer charge on the fill gallons, which is nice.
Thanks, D
