I second that, my Taylor K-1000 (OTO/pH) is my daily tester. I only break out the 'big kit' once a week!

Once you get used to using OTO it even becomes useful at high chlorine levels since it does not bleach out like DPD. Just realize that it is testing only total chlorine. However, if you are on top of your water and your weekly test does not show CC then you can assume on the daily tests that the TC is pretty much the FC when your water is stable.
