Increased consumption

Your sodium hydroxide recipe. And your sodium BiCarb recipe.

When my PH reaches 8.50 my dosers switch from hydroxide to BiCarb.

The hydroxide recipe is twice as potent as the bicarbonate . For the hydroxide, you double the alk part and dose that as the Part C. For the bicarbonate recipe, you match Part C to the alk part. If using both, add both Part C determinations together and add the total.

As you finish a gallon of hydroxide, add 182g of Balling Part C.

As you finish a gallon of Bicarbonate, add 91g Balling Part C.

You can mix either in a gallon container.

You sure? The TM recipe is 1:1:1.

Balling Part C uses a concentration to match sodium bicarbonate. Since the Sodium Hydroxide is double the strength, we need to add double of the Balling.

26.67g of part C for 1 mol of Sodium Bicarbonate.

1 mol of Sodium Bicarbonate is 84g.
The equivalent in Sodium Hydroxide would be 40g, and 53g for Sodium Carbonate.

Oh, you were quoting grams not mL. My mistake, but that might confuse folks since I presume you mean grams of the dry solid while I was giving mL of the dosing fluid.

I apologize. I didn’t read through the whole thread. I thought they wanted to know how much balling to make a dosing solution.
