Ahh I see what you're saying. I don't think N03 and P04 are always good metrics for determining nutrient levels. While my N03 and P04 are low, im feeding my fish and corals quite heavily with a variety of foods/amino's etc (adding nutrients) but also exporting heavily with filter carbon, aggressive skimming, carbon dosing, water changes etc, to keep N03/P04 low. There's also probably a wide range of interpretations on what 'nutrients' consist of. But either way, things seem to be running ok. (other than a bit of green slime).
