I'm new to testing my own water and am using the TF-100. It's all straightforward but I'm getting mixed chlorine results. The daily "yellow tests" gives me a TC of around 3 and the R-870 shows a pretty consistent 4.5 to 5.0 FC and 0 to 0.5 CC. I took my last test to the pool store to verify and they show 3.6 for FC and TC. All my other results were pretty close to theirs. Any tips on closing the gap/getting closer results? I have a SWG so I'm not sure if the difference is a big deal but don't want the chlorine too high (I've got little kiddies that can't wait to get in the pool).
Thanks for any help. This site is Great!!!
