Potassium is 39.098g/mol. Since you got two K the percent potassium is 2 * 39.098 / 138.205 = 56.58% potassium when measured by mass (or weight). **Q: How much should i add to 1 galon of water to make a solution similar to general hydroponics ph up?** A: There is no set answer for this. Type of water will you are buffering will determine what the needed ratio would be. That said this is very strong and even after adding all my needed nutes ( I mix strong, cal mag, 0-10-10,etc.) I use 1- 1½ tsp per gallon which brings my ph into the normal range. I use distilled or rainwater. Its very strong stuff and well worth the savings vs ph up/down. **Q: Seller, is this k2co3? thanks** A: To our knowledge, yes, this is. This is a food grade Potassium Carbonate primarily used in beer & wine making manufactured by Armand Products Company.

You’ll be surprised.. ### ⭐⭐⭐⭐⭐ Item arrived quickly, was packaged well, and works great. *by I***R on February 16, 2026* Item arrived quickly, was packaged well, and works great. ### ⭐⭐⭐⭐⭐ Works for me *by W***E on December 27, 2025* I successfully use this to raise the pH of food stuffs. I bought it in February 2024, and my sensitive nose could not detect any smell. I use it for hydrating faba bean protein concentrate and for an alkaline brine for hydrating beans (1 cup dry beans, 700mL water, 28g salt, 7g K-carb; 8–9 hrs room temp + 10–11 hrs in fridge). I do use a citric acid stop bath (4g/2.5c water) for 5 minutes to freshen the beans up and then they taste great.
