I sometimes type whatever aquarium question is on my mind into google and lurk whatever forums allow visitors to read them. Anyhow, i saw a post (elsewhere, not on ours) about how the level of acceptable nitrate in your tank is different if you're planted vs. Not planted. Anyhow, I'm no where near ready to call my tank "planted", but i was curious if A.) there's any truth in that, and B.) What are the acceptable levels for NO3 if you ARE planted, and C.) At what point can you call yourself a "planted tank" Is there some ratio like X-many plants per gallon?
