Normally I use a Taylor test kit with the yellow side for chlorine and the red for PH. It came with a bottled labeled R-0600 I believe. I went to the local pool store and bought what I thought was the same kit but this one came with R-0001 and R-0002 for the Chlorine test. Is there any advantage to one kit over the other? I have a full TF100 kit for my other tests but I use this for my basic day to day checks and want to make sure its still what I need and I am wondering why the 2 different kits? What does the one with one bottle of R-0600 do vs the one with R-0001 and R-0002?
