Too funny. I was just reading this to try to find how much KHCO3 to add to raise my KH using reconstituted RO.

That is quite the coincidense.
I was reading it as I heard Potassium Bi-carbonate was good to dose for anubias fungus. Apparently, the fungus doesn't "like it".

What I'd like to know is where have all those (and other) old members gone?

In case anyone is still wondering about using potassium bicarbonate to raise KH I came across the answer.

67.7 grams of KHCO3 in 500 ml of distilled water

1 ml / gallon = 1 dKH
1 ml / gallon = 14 ppm K (potassium)
