Hi my pool is Ag 15ft round vinyl liner 36" deep so I guess 4000 gal.
We just replaced the liner again last week. Test results today are:
I can't get the TA test to change from very dark pink. It changes at 11 drops and stays there. Also on the CH test when you add the R-0011L it says that red indicates calcium, but it changed to pink. Then I added the 3 drops of R-0012 to get the blue that gave me the CH result of 30.
I added about 3 pounds of baking soda over the past 2 days. Thanks. Carolyn
