You are correct that sodium carbonate and sodium bicarbonate are
different. 

Fortunately where I live is semi-rural and a small grocery store did
carry it. I am not sure if it is something that bigger chain stores
would carry.

However you can go to a pool supply to get alkalinity increaser. You
have to be careful not to get the sodium hydrogen carbonate which is
also baking soda. I made that mistake initially.
