With the amount of bleach I used to clear up my swamp I pretty sure I was way over that and never bleached out. I am assuming by bleach out you mean it goes clear which would be a reading of 0 ppm. I only say this because my results over the week seem to contradict what your saying. Either I am screwing up the test pretty bad or something has changed with their kit.
On a side note I have been keeping reef tanks for almost 20 years so I am pretty good with test kits as we had to test same things with the exception of CYA and Chlorine and a few things we are not concerned with in a pool.
Why do you recommend both an OTO and a DPD-FAS test kit for chlorine seems redundant if they both test the something or am I missing something.
