My daughter ask me to come out and take reading on her pool as she could not get it to clear up. 25,000 gal IG vinyl with sand filter. I have an FT-100 test kit. CYA 60, FC .5, PH could not be read as color was yellow way below 6.8 on the test tube. TA added 2 drops of R-0007 than 5 drops of R-0008 and the test water turned red not green. Where do I go from here?
