So I have the API liquid test kit and have been running pretty low on the nitrate test solutions. They havent expired, but are running extremely low. Just purchased new solutions and dida test with both sets. Equally shaking and pounding each set I did a test and the newer test showed roughly 5 or 10 ppm nitrates while the old set illustrated more like 30 or 40. I have been doing partial WC every few days because of the high nitrates that my old test kit was producing. Has anyone experienced something similar? Which test is correct?
