FC=6, PH=7.6, CYA=40, CC=0
I have been trying to keep my pool FC at 6 each morning and the following morning it has gone down to about 2.0-2.5 powder test, so I add about 1 gallon of LC. Getting expensive, but OK if that is what I have to do. However, this morning when I measure again the FC=2 with powder, I tried the drop test and it looked more like 5 to me, definitely more than 3. Which reading is more accurate? I always assumed the powder?
