It's a nitrate factory. Factories are good,they produce things but not if they make something you don't want. Nitrate isn't a bad thing either; it just is. Water changes don't do much for nitrate reduction long term though I think they are very improtant for many reasons. Many aquaists achieve nitrate lower than .2ppm( upper reef nsw levels) even with heavy feeding.
What contradiction? What conjecture?
