For those of you that measure nitrate levels in your *fish only* tanks, what do you think the "average" amount of nitrate production would be??
If I define
R= Weekly rate of nitrate production
N= Number of weeks until a water change
F= Percent of water change, expressed as a fraction (25% = .25)
SS=Steady state nitrate level in the tank
For example, RTR stated in his Aquasource magazine water change article that his nitrate levels were 10 ppm steady state, and that his water changes were 20% every week. So, the weekly nitrate production level is R=10*.2/1= 2 ppm nitrate produced weekly. I *wish* I had that kind of disicipline to stock my tanks that low. My goldfish tank when it was fish only took something like 50% weekly to keep the nitrate level at 20-40 ppm, which meant a weekly producti
