Hey,
I just found an very nice page to regulate ph & kh with baking soda, have done a experiment, and work out great, just as is says.
My ph was 5.5, kh 1. Added 1.8 tsp baking soda - ph went up to 6, kh to 2.
This program works out how much baking soda you should use to raise your kh to your preference, and also calculates how much this will raise you ph.
Have a look!!!
