"Recipe" for RO/DI water

Potassium Chloride is also what is used in water softeners as a Sodium
Alternative. Costs around $8 for a 40 lb bag. A good brand is Morton's
(yes the salt company). Check out your local Sears, they carry it.

Thanks Buzz, good info...I didn't know that was the same.

Thanks for the input.
OK, I had the baking soda in the cupboard, and the Epsom salt is ubiquitous
in the stores so that was no problem either. Both pure with no additives.
Now the problem. I couldn't locate the potassium chloride water softener
salt. I did find a few KCl table salt substitutes...but they aren't pure.
The "purest" brand I could find included the following ingredients: Fumaric
acid, Tricalcium phosphate, and Monocalcium phosphate.
And regarding the CaCo3, I was able find the 600mg tabs, but again, not
pure. They include Cholecalciferol (Vit D), Croscarmellose, Cellulose
coating, and Vegetable Magnesium Sterate. Again, this was the "purest" brand
I could find.
My eyes are still watering reading all that fine print on all those
bottles!!!
Are these ingredients OK, or should I keep looking for a more pure source?
Thanks,
Bob

They are not that critical, but I think I'd make up a 50 or 100 gallon
batch of everything except the Calcium Carbonate. That is going to come
out at roughly 175ml of powder for 100gal, (assuming US tsp is the same
size as a UK tsp), so 1.75ml of powder per gallon of water + the CaCO3 -
or 1/3 tsp/gal. You can work out the CaCO3 separately.

Thanks again Roger,

A teaspoon in the US is 5ml. is that the same as in the UK?
What effect will this recipe have on the dKH & dGH? Will it raise each by
about 1 degree? More or less?

And I actually plan to make much more than ten gallons worth at a
time...seeing how I have a 180 gallon tank that wouldn't go very far!!!
