The reason I ask. I have been testing with API for a while. I also have the LFS test to backup my readings.

Lately I have been testing high nitrates in the 20-40ppm with the API test kit and the LFS is testing 0.

Thinking about upgrading to a better test system. Thought I would buy a nitrate only kit. Avoiding buying the ammonia and nitrite if I do t really need them anymore.
