Just wondering....What level does everyone keep their nitrates. Mine are less than 20ppm with a 40% weekly water change. I was wondering if I could stretch to two weeks if they stay under 40ppm? Any opinions?

My well water comes out of the tap at 20ppm. My tank water stays at about 30 to 40ppm, with weekly water changes (50% to 60%).

I have had no problems with nitrates being at 40… :)

I try to keep mine below 40 ppm. If yours is staying at 20ppm with weekly water changes, you should be able to stretch the changes to two weeks. Give it a try and test it.

I try to keep mine 20ppm before water change and 10 ppm after water change. The fish are VERY happy.
