Mixing Ferts to Make a 1000 ML Solution

[Crispino Ramos]

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.
