Potassium nitrate....should I?
hi all! my friend told me i should start to dose Kno3 twice a week as a fertilizer to supply potassium to my plants. I already dose trace elements twice a week and MGS04 once a week. However im afraid that my nitrates would increase (they are already around 25ppm). Should I dose it? Im a newbie to planted aquariums and im at a loss with all the conflicting info.
