I use Tetra test strips most of the time in my fish room. They read zero chlorine on my tap water. I know this is wrong so, I use Tetra total chlorine to test my 3 stage filter water to make sure they do not need changed for auto water changes. My tap is between 2 and three ppm total chlorine. We have chloramine not chlorine. I think this would be worth mentioning when talking about testing water.
