When you enter in to a situation where all your nutrients are either in a form you can't test for, or they're dynamically taken up by something the second they're produced, you almost need to rely on what your tank is telling you than what you get from a test kit.

your getting 0.000 on the ultra low test kit?

hanna for phosphates show 0.00 always, and Red Sea Nitrate kit with the little colour wheel has never had a colour change. I'm not sure if that's the ultra low range kit though, there's obviously some there in trace levels for things to still be growing.

Is there a kit that tests at a lower range?
