Baking soda (sodium bicarbonate) raises total alkalinity — enter your current and target reading to find exactly how much to add.

Pool-store "alkalinity increaser" or "pH increaser" is usually pure sodium bicarbonate — the same thing sold as baking soda, just packaged for pool use. Ordinary grocery-store baking soda works identically at a fraction of the price.
Yes — it's the same sodium bicarbonate sold as pool alkalinity increaser, just without the pool-store markup. Buy it in bulk for the best price.
