I'm just wondering something about the OTO chlorine test.
In the details of the kit it says "normally used daily".
I also read in the extended test directions " Above 2 (ppm) accurate readings become difficult and the precision is very low. If its not precise above 2ppm and recommended levels are 3-7, I just can't figure out any time to use this chlorine test. Does anyone use it to decide how much chlorine to add or just as a quick simple look to make sure its not at 2 or less?
So who uses it daily?
Who uses it when, why, how often?
Who says if I'm getting my testing stuff out, I mine as well do the accurate one and do the FAS/DPD test instead?
