    I would like to make a 1000 ML solution of potassium nitrate and potassium phosphate for dosing a 20 gallon heavily planted tank. How much potassium nitrate, potassium phosphate, and water would I need to mix? How much of the fertilizer mixture should I apply to a 20 gallon tank daily?

    You could daily dose 5mL/day, 35mL/week

    • Distilled water
    • KNO3 (21 tsp)
    • + KH2PO4 (3* tsp)
      Top off to 1,000mL
    1,000mL NPK Stock​

    * 4 tsp, KH2PO4 w/ water low in phosphate.
    Mine is 2ppm w/WC from the tap, food, etc.

    Wet's calculator will help you explore that idea.
