	Nitrates: how high is too high?
LMuha Mega Fish Posts: 908 Kudos: 1144 Votes: 183 Registered: 17-Mar-2003	Everyone says you shouldn't let the nitrate levels in your tank get "too high" over the "long term." But what's the definition of "too high" and the definition of "long term"? 40 ppm? 80 ppm? 100 ppm? Two weeks? A month? Six months? At what point (time-wise and level-wise) do problems start occurring? Just a curiosity question -- I do weekly water changes, so 40 ppm is about the highest level of nitrates I have in my tanks.

Personally i've had better luck with my tanks going with the 40ppm idea. That's not to say i've never let them get as high as 100ppm, but I do try not to let them get above 40ppm.
