Most pool owners have no idea that they can use household baking soda in their swimming pool to adjust the PH and the alkalinity. The most common thing sold to swimming pool owners is something called Alk up or total alkalinity. The problem with buying alkalinity from your swimming pool dealer is that the price is way more expensive then regular baking soda.
Instead of wasting money on over priced buckets of total alkalinity you can use the baking soda found right in the local supermarket. One of the most common brands of baking soda you will find in most stores is Arm & Hammer baking soda. If you buy the large box of Arm & Hammer baking soda on the side you will see a chart on how much you should add to raise the total alkalinity according to your swimming pool size.You can also lower your high pH levels with baking soda.
To save even more money on the cost of your total alkalinity you can shop at discount home centers and buy your baking soda in bulk. This can not only save you money but can also save you a trip to the pool supply store in the middle of the summer when you need more pool chemicals.
