Note that phosphates will through off you CO2 calculations. Are you using

I believe it is accurate I am using an Aquarium Pharmaceuticals test kit
and
have tested it several times.

If the measurements are right, your CO2 level is around 57 ppm. I'm
surprised your fish aren't showing signs of distress. Are you fairly
positive your KH test is reliable?
