Baking soda can be used to raise the pH in a swimming pool.
If you own a swimming pool, it's important to maintain the pH in a range between 7.2 and 7.8.The chlorine you add to the pool doesn't sanitize well if the pH value is too high.The water becomes corrosive when the pH is too low.Adding an acid will lower your pool's pH.Baking soda can be added if the total alkalinity of the water is low.If the alkalinity is high, you should use soda ash to raise the pH.
Whether the water you use to fill your pool comes from a well or a municipal water source, it's more likely to be alkaline than acid, and you have to bring the pH down to properly suck the chlorine out of it.Adding an acid to the water is how basic chemistry tells us to do this.If you want to lower the pH in your pool, you can pour in a weak form of hydrochloric acid, but many pool owners prefer dry acid because it's a powder and safer to use.
The total alkalinity is a measure of the water's ability to maintain a stable pH.When the pH and alkalinity fall, acidic water can cause itching skin for swimmers and may stain or corrode the pool liner, ladder and other pool components.Adding baking soda to the water raises the alkalinity and pH.
Baking soda is not always the best chemical to use.In rare cases, the total alkalinity may be in the proper range of between 80 and 120 parts per million when the pH is below 7.2.It's better to use soda ash to raise the pH.It doesn't affect total alkalinity.
You don't have enough baking soda in your kitchen cupboard to treat 10,000 gallons of water.Large quantities of baking soda can be found at pool supply outlets.If you buy from a pool supplier, the container will tell you how much product to add to your pool.If you buy baking soda, make sure you read the label carefully.
You should also test for total alkalinity when you test the pool pH.The amount of baking soda you need to add depends on how low the pH is.If you buy the baking soda at a pool supplier, the instructions on the container will specify how much to add, based on current alkalinity concentration and the volume of your pool.It's important to buy enough product.For most applications.You will need more than 10 pounds.
Test the water with test strips or a pool test kit.If the total alkalinity is below 80 parts per million, add baking soda.If the alkalinity is in the correct range, use soda ash to raise the pH.
The container has instructions on it.If you want to add the baking soda to the pool, you can either pour it in or diluting the water.Baking soda can be poured straight into the pool from the supermarket.Rather than pouring it in one spot, dust it over the surface.
