Hello, I have the TF-100 test kit, which I love, and understand. And daily I use the Chlorine Test (OTO), which only measures up to 5. I need my water to be at a 6 each day, is there a test kit like the OTO that has up to 6? I know I can do the test with the powder & the drops (sorry donít know the real name of it) but I would love an easier one to do daily. Any suggestions? Thanks!!
