I am using the TF100 test kit and when I use the complete kit chlorine measure I get 3.5ppm but when I use the little quick test that came with the kit for Chorine/PH it reads in the 5-10 range. Just wondering about the accuracy of which test to follow. Is there something else that throws off the accuracy of either test? We filled this pool early September and I'm still working the CYA up and am now at about 40. PH is just below 7.8 so I need to figure out where to buy the muriatic acid.
Thanks for any info!
