Where do you draw the line with NItrates?

Well yeah I guess danger zone isn't the right wording for 40ppm of nitrate. How about "action stage?" (as in, time to do something about it).

Sounds good to me.


I don't let my nitrates get past 40-50 range. If it goes past that, I just don't feel right... almost guilty. lol

dude 100ppm isnt even something to get alarmed about. you should do a wc, but unless ur keeping something uber sensitive dont worry about 40ppm

80 ppm is around where it will start to become toxic to your fish and around 160 ppm is dangerous but i do my best to keep my tanks below 30 ppm at all times
