My Tank Thread
The recipe developed by Jim Welsh that uses sodium sulfate assumes, I beleive, that the sodium sulfate is anhydrous, so you need make no corrections:
Jim's recipe (with some text added by me):
Part 1 - The Calcium and Magnesium Part
Dissolve 500 g of calcium chloride dihydrate plus 261.2 g of magnesium chloride hexahydrate in enough water to make a total volume of one gallon.
Part 2 - The Alkalinity and Sulfate Part
Dissolve 374.7 g of sodium carbonate (594 g of baking soda that has been baked; = 3.535 moles of sodium carbonate) plus 68.7 g of sodium sulfate in enough water to make a total volume of one gallon.
This recipe is the same strength as Randy's Recipe #1 (e.g., BRS). To make these two parts with the same strength as B-Ionic, then multiply the amounts of the salts by 1.5 (but note dissolving the carbonate can become challenging).

New DIY Two Part Recipes with Higher pH Boost
Here's a first crack at what may end up being multiple possible recipes for a DIY two part that either has a higher pH or can be made more concentrated than traditional two part recipes. This one has about twice the pH raising effect compared to a carbonate based two part, per unit of...
