I agree with Tom's suggestion, I would raise the KH above 0.

But there is a post at the end of this page that suggests a different equation to measure CO2 levels that doesn't use KH as reference. Perhaps it may work for you, but says you will need to have very precise PH readings:

Hope that helps
