Am wondering at what levels are NitrAtes a concern for those with plants/fish?
Judging from readings I have been measuring with API test and fish load in my low tech low maint 80 gallon tank, I can't help but be a bit concerned at 80ppm readings with 1/4 tsp KNO3 every other week and once a day feedings.
Have resisted the urge to perform water change in non CO2 tank and am simply reducing the amount of KNO3 I am adding but an curious as to what readings or levels do others see as normal or abnormal?
My fishes exhibit no signs of discomfort or abnormal behaivor and plants are doing well, just wondering what those who are more expierienced think?
Have never run a tank with NitrAtes over 20 ppm and would welcome thoughts or opinions . Thanks in advance, Lee.
P.S. should I even be relying on the results from API test ?
