    Borate/Chlorine Question

    I'm fairly new to this and have been getting "pool stored" for awhile...until I came across this site! I have the TF-100 kit, speed stir, salt test kit and borate strips on order so I can stop getting +^#^%#'! With by my pool store. 7 days ago my pool store told me my free chlorine was over 16.59ppm, borate 35, ph 7.4, hardness 219, alk w/stab core. 145.1, cya 33. Today they said free chlorine 2.25, ph 7.6, hardness 217, alk w/stab corr 122, cya 37, borate 0. I non ch shocked my pool, and dropped my swg to 10%. They told me that my 35 borate from last week did not read correctly because of the high free ch reading. Is this true? And w/normal use in 7 days can my free ch go down that much? I have a 28,000, rectangle, auto cover, swg, jany var speed 1.5 (running at 1950rpm 24/7), and heat to 89degrees. I know I need to wait for my kit, but any help in the mean time would be appreciated! Thanks!

    Have you actually added borates to your water? If not, it is zero.

    I am not sure of the interaction between the chlorine and borates with the test though.

    What is the CYA level (aka Stabilizer)? With a rational level of 40 and full sun you could drop 1/3 of FC a day.

    They told me my cya level was 37. Aquajunk test strip says between 0-30. I added two huge 3-5gallon buckets of supreme last summer. Probably added 8-12 inches of water since.
