I hired a pool chemical company to treat and balance my pool but I want to be able to test it periodically myself. First I bought a DP kit and the readings for chlorine levels weren't matching what the pool company was saying. They said I needed a OTO kit so I got one and the chlorine test always shows up orange instead of yellow. So I called and they told me that liquid chlorine treated pools show up on an orange scale instead of yellow when using a OTO kit. Is this correct? If so, is there an orange scale sheet somewhere I can print off and reference when I am testing myself? The chemical guy didn't know of any.
Thanks for any help you can offer!
