I always assumed below 20 ppm was ideal, but after reading around it seems like it is more like 50 ppm.
My 55g tank has 6 goldfish in it, and I flip when it gets to 20 ppm. It is planted, but not too heavily (they eat them or dig them up). I think I'm being paranoid
What are the nitrate levels on your tanks usually at, especially right before your water?
