I was looking at Sera KH Pond... the content is Potassium Bicarbonate. Can this do instead of Baking soda which is sodium bicarbonate?

In terms of raising KH, there is no difference between potassium bicarbonate and sodium bicarbonate (AKA baking soda). But you will find baking soda much cheaper compared to Sera KH pond.
