So I started dosing high nutrient fertilizers in my 120g about 2 weeks ago. I just did a test for nitrates and they are about 80ppm. The fertilizer when dosed in the correct amount, the fertilizer adds 7.5ppm to the tank. I don't believe that there are any other contributing factors in the tank other than the fertilizer. Am I dosing too much? Is that level of nitrates ok? I'm not having any problems because of the high nitrates at the moment, just worried if something might happen
