I know I should have a better test kit, but I don't right now. I am trying to SLAM my pool, and using the chlorine test that uses 5 drops of the yellow reagent. I thought that I read that you could dilute your pool water with distilled water, 50/50, and then double the result. This makes sense to me. My question is, can I add 1 drop of reagent, and then multiply my result by 5? I get a 100% pool water sample, and add 1 drop of the yellow reagent. The result reads about 5 ppm. Can I safely conclude from this that my actual chlorine level is 25?
