If nitrate is truly 0 and phosphate is truly .1 ppm, why not just remove the offending Cheato and see what happens? Nitrate may rise on its own. The GFO might need to be changed a little more often during the process though. A little extra feeding might speed the process, but be conservative.

I think you missed his phosphate number. Its actually 0.01 or less. In that case, I don't think there is any reason to be conservative on extra feedings. IME it takes A LOT of extra food to go from 0 to detectable, so you can be quite aggressive with extra food and not worry about overshooting too quickly (depends on food too obviously). And instead of changing out GFO more often, I would quit it altogether until phosphates start to get above .03, then it could be time to evaluate its reintroduction.
If you are dosing products to up the nutrients, then you definitely need to be conservative.
