So, I got into a discussion with someone about overstocking tanks (e.g. 10 fancy goldfish in a 3ft tank) and my stance was that it would be inhumane due to space and water quality concerns.
But there was this guy who claimed that it's perfectly fine because "as long as you have enough filtration you can achieve 0 nitrates". He shares his experience with his "3 ft tank with numerous small tetras, corydoras, altum, discus, plecos that has 0 nitrates" with 2 Eheim Classic 350 filters with 3-4kh of biohome media.
Sensing something amiss, I enquired further and it turns out that that he has peace lilies growing out of his tank as well, which I think would be the one responsible for 0 nitrates.
If anyone is interested in what the guy said exactly, click here.
So, my question is: Can one reasonably achieve adequate denitrification using canister filters to bring nitrates down to 0?
