Using – Mixing Dry Chemicals for Seachem’s Dosing

Seachem’s products are a little expensive, but they are very good. I know some people would like to cut the cost some and use some of the dry fertilizers that are available.

The following dosing solutions will be practically the same strength as Seachem's macronutrient products according to the online calculators. You then go by Seachem's recommended dosing amounts on the calculator.

Dosing Solutions
- Add 62.2 grams or 11⅛ tsp of KNO3 to 500 mL of distilled water for F. Nitrogen Substitute
- Add 3.5 grams or tsp of KH2PO4 to 500 mL of distilled water for F. Phosphorus Substitute
- Add 51.0 grams or 8 tsp of K2SO4 to 500 mL of distilled water for F. Potassium Substitute*

*(This amount approaches the maximum solubility of K2SO4 of 12 grams per 100 mL of distilled water. You will probably need to shake the container each time prior to dosing.)

Online Calculators Used:

IMO, you may omit F. Trace even though it is included in the calculator.

I do not have a substitute for Flourish, F. Excel and F. Iron at this time.


I hope this helps you. Let me know if it works well.
