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

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!!!
