I'm looking through the ADA catalog at all of the pictures of aquariums full of lush growth. Each picture also lists some of the tank parameters and for each one the NO3 is <1mg/L and if I'm correct 1 mg/L equals 1 ppm. The section on ADA ferts says that in a planted tank nitrogen and phosphorous are generated in excessive amounts and potassium and traces are usually lacking and need to be added. So I'm sure you know where I'm headed with this. Do we need to be adding NO3 or is it just potassium that's needed? I'd really like to know what you all think about this and any experience anyone has. It seems both methods yield successful results.
