hey all im a new member and my question is for a 330ltr tank with no nitarte's coming from the tap water how much kn03 do I have to add to achieve the 10ppm level for the nitarte reading...??? My phosphate level is at .5ppm. And also whats a good fertilizer or brand for adding potassium to reach 20ppm..
