They are the highest quality products available. Exceeding most or all of the supplements availabe. Most experienced DIY people get the supplies from them.
I only get the Mg Chloride & High Purity Calcium Chloride (food grade Anhdyrous Calcium Pellets).
I use Arm & Hammer baking soda (and bake for 1hr at 350) for the Alkalinity part and Espon Salt for the Mg Sulfate. I purchase both at Costco.
