Through the constant trial and error process, I came up with a formula for my 20 gallon tank to get my nitrogen level at 20 ppm; it was 1 ml (Seachem Nitrogen) daily, 3 ml after weekly 40% pwc. This worked very well for the first month I started with this regime. After the that month though, my nitrogen level started creeping upward and after two additional weeks, it topped at 60-80. I stopped dosing altogether and did a pwc to get it to around 40.
I have not added ANY nitrogen to the tank for about four weeks now and my nitrogen level has remained at 20. How is this possible that I do not have to add nitrogen anymore?
I still dose potassium(The same regime as the nitrogen), but have decided to scale that back to just 3 ml weekly. Am I correct in assuming that the potassium level should be fine? I have no interest in purchasing an expensive potassium kit, and prefer to use the plants as my indicators; Which are doing well.
Side note: I do have about four plant tabs in the bottom under the big clumps of plants, and do not dose Phosphate because my tap water (I am told by the lfs) has plenty of that. I do dose iron once a week as well.
