Isn't the fact that the plants need nitrates the reason that many planted tanks don't see nitrate levels at all?

Honestly, my Nitrates have always stayed around 40ppm, (before and after adding plants). However, if they are reading 0, the plants will be lacking the essential amount of Nitrogen in order for them to flourish. This is why most heavily planted tanks require Nitrogen replacement.
