    Hanna checker ... &Itemid=29

    Has anyone tried one of these testers?
    In the reef aquarium hobby these have really held up and people love them.
    I was excited to see that they have one for free chlorine since this will be what I test for the most.
    27' AGP, stenner pump, 30 gallon holding tank, 2hp two speed pump, cartridge filter, 12.5% liquid chlorine.

    I would not depend on this for chlorine at all. If you want dependable numbers, go with a good drop test. It might be ok for pH if you keep it calibrated and maintained, but that's it.

    Looks like it only tests to 3.5 ppm free cl, prob not to useful in most cases.
