Hahhah, I like that you just brought that up 'cause I went through some more digging and actually came across a few threads that said more older/established tanks with plants will still have readings of nitrates xD From what I got, it seemed the plants still help keep nitrates in check but obviously since it's a closed ecosystem that's still a variable which needs an eye kept on it... anyway, I'm sorry I feel like I'm drifting from the original reason for this post... I'll stop now
