We’ve all heard about pH balances and pool maintenance, but what does baking soda do in a pool?

Also known as sodium bicarbonate, it is naturally alkaline and has a pH level of 8. When the pool is looking a little cloudy, it can be time to raise the pH levels. Baking soda raises this, and the alkalinity improves clarity and alkalinity.

The pH levels need to be between 7.2 and 7.8 so use it to increase the level should it drop below this number.

You will find that a wide variety of pool products use baking soda as their active ingredient.

Will Baking Soda Lower Chlorine Levels In a Pool?

Although it will raise alkalinity in a pool, baking soda will not lower chlorine levels.

To lower chlorine, you can stop adding chlorine for a while and allow the UV rays of the sun to evaporate the chemicals.

Otherwise, baking soda does not affect chlorine levels.

In general, using baking soda to raise pH in a pool means adding 1.5 lb of baking soda per 10,000 gallons of water.

This will increase alkalinity levels by around 10 ppm. This means that if alkalinity is lower than 7.2, you will need to add 3 – 4 lbs to return the water to an optimal level of alkalinity.

Anyone new to pool maintenance should start by adding less and retesting the water to get a gauge as to how much is required.

How to Lower the PH In Pool Baking Soda?

Using baking soda in a pool to lower pH is not possible. To lower pH, you will need to use a pH reducer.

The activity ingredients should either be muriatic acid or sodium bisulfate and are available in pool supply stores.

How Much Baking Soda to Raise Alkalinity In a Pool?

The ideal alkalinity level in a pool is 100ppm. The standard method requires 1,25 lbs of baking soda to raise the pH level of a 10,000-gallon pool by 10ppm.

This means you need to add 12.5 lbs of baking soda in a 100,000 pool if you want to add 100ppm of alkalinity.

Be sure to avoid adding baking soda on a windy day as you will lose a lot of the powder in the breeze.

Wait for around 6 hours before reentering the pool as this will give the baking soda the best chance of working.
