Thank you Ade, Jerry and Liz for your kind answers :-)
So basically potassium bicarbonate has the edge as it dissolves quicker and
My Tap water has a ph of 6.4 and a KH of about 2d, GH pretty close to zero.
I've also heard that Potassium carbonate removes chlorine from tap water as
well. I wonder if Potassium bicarbonate does?
