My well water has over 50ppm nitrites (tested by a lab), so I purchased dry K2SO4 Potassium Sulfate and KH2PO4 Monopotassium Phosphate to dose rather than using KNO3 Potassium Nitrate. All the EL instructions assume you need KNO3. I’m mixing 5ml wet per 20 gallon aquarium into a 500ml bottle. Is the following formula correct?
KH2PO4 = 2 ½ teaspoons
K2SO4 = 6 teaspoons
If the above is correct, can I scale this value for varies size tanks?
KH2PO4 (x) 2.4 = K2S04
Thanks
