    I was paying for RO water from one of the machines, and it was testing at .8ppm. So I was paying 35 cents a gallon for phosphates. I now have a DI resign I'm using, with replacements cartridges costs its about 24 cents a gal, and everything is at 0 now.

    Edit:
    Also wanted to add, I don't have an RO unit, so I go threw the DI much faster, if you have RO/DI it will be even less a gallon.

    Which test kit are you using? I can't hardly tell the difference from .25 or 0 on the API kit.
