This month, I had bought some KNO3 in dry form for my El natural tank since it's showing signs of a potassium as well as a nitrogen deficiency.
I had added 1/8 of a tsp(actually, a little less then that) to a small amount of water then added it to my 10g tank. It raised my nitrates up from 0ppm to 10ppm. What I would like to know is how much would that amount have raised my potassium up to? Should I add something else to the tank like potassium sulfate, etc.? I'm new to fertilizers.
Thank you.
