Will baking soda kill algae in a pool? No, baking soda doesn’t kill algae directly!

Read on to find more information about the positive effects of baking soda in pool maintenance. You will learn how it works and how it can be used for this purpose, too.

The Science Behind Baking Soda’s Cleaning Power

Most households have Arm & Hammer Baking Soda, but its potential in cleaning pools isn’t well-known. It isn’t so for its cleaning uses, from brightening teeth to cleaning the tile grout in bathrooms and sinks. While the latter also applies to tiles in the pool, there are other reasons for its use in algae removal.

Pool maintenance involves measuring and maintaining the water’s appropriate pH levels. Ideally, the water in pools should have between 7.2 and 7.8 pH levels, with seven on the pH scale being neutral. As such, the water should be slightly alkaline.

Unfortunately, pool water is more likely to become acidic without proper and prompt intervention for many reasons.

First, rain with its 4 to 5 pH levels will increase its acidic content. Second, the combination of organic debris, body fluids from swimmers, and chlorine additions will also decrease its pH level.

The result: The pool water becomes acidic over time. It can cause corrosion in the pool fixtures and tiles as well as cause health issues to the swimmers. More importantly, the highly acidic environment can encourage algae overgrowth.

The simple, affordable, and safe solution: Use baking soda! The white material has an 8.3 pH level, an alkaline substance that counteracts the acidity of pool water.

Also, its bicarbonate ions either increase or decrease the pH level to 8.3 of many things they come in contact with.

Using Baking Soda In A Pool

But don’t just pour boxes upon boxes of baking soda on your pool! You may need other cleaning products to remove algae from the pool effectively

You can use algae killing products on the pool first. Make sure to follow the instructions of the manufacturer about its proper use, especially when adding it to the pool water.

Then, allow the algae to kill the product to circulate through the water, a process that can take 6-10 hours.

Afterward, sprinkle generous amounts of baking soda on the algae-affected area. Use elbow grease in scrubbing the area until there’s no sign of algae!

Of course, you can use baking soda as an alkalinizing agent in an acidic pool! As a rule of thumb, you can use a 1.25-pound box of baking soda to increase the alkalinity of a 10,000-gallon pool by as much as 10ppm.

Let the baking soda do its work by allowing it to circulate for 6-10 hours.

Overall, baking soda is an inexpensive, easily available product that every pool owner should have in stock alongside other pool materials and supplies. But look beyond its pool-related uses by reading books like Baking Soda: Using Baking Soda and Loving It and be amazed by its practical applications.
