How do you fix high alkalinity in a pool?

There are two ways to increase your swimming pools alkalinity level: sodium bicarbonate (baking soda) or any type of alkalinity increaser product. If you choose to purchase an alkalinity increaser product be sure the product is made from sodium bicarbonate, which is the main substance used to raise pH.

How do I lower the alkalinity in my pool fast?

Method #1: Use Muriatic Acid Muriatic acid (hydrochloric acid) is the most common way to lower your pool’s total alkalinity level. With a pH level of between 1 and 2, it’s inexpensive and strong enough to kill mold, remove rust, and rid the pool of calcium deposits.

How do I lower the alkalinity in my pool without pH?

If you add acid to the pool to reduce the pH, you will also reduce the Total Alkalinity. If you add acid to the pool to reduce the Total Alkalinity, you will also lower the pH. This is true, no matter how you add it. The same holds true when a chemical is added to increase pH or TA.

How do you remove alkalinity from water?

The feed of a mineral acid will neutralize the alkalinity of water. Hydrochloric acid, sulfuric acid or a combination of these can be used. This process converts the bicarbonates and carbonates present into carbonic acid.

Does high chlorine affect alkalinity?

Most people know that chlorine is an important chemical in keeping pool water safe for swimming. But adding too much chlorine can lower your pool’s pH as well as its total alkalinity.

What causes high pool alkalinity?

Alkalinity rises because of excess hydroxide in hypochlorite chlorines. And in the case of calcium hypochlorite (cal hypo), there is not just excess hydroxide, there is excess carbonate too.

Why is my alkalinity so high?

One of the most common reasons why alkalinity levels are so high in pools is because of too many chemicals. This is usually the result of human error. However, for people who live in a geographical area that experience acid rain, this can be a common problem. The acid rain can continuously change your pool’s pH level.

Will baking soda lower pool alkalinity?

Baking soda, also known as sodium bicarbonate is naturally alkaline, with a pH of 8. When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity.

Will alkalinity decrease on its own?

Now it’s important to note that high alkalinity levels will naturally decrease over time on their own. But high total alkalinity can precipitate other issues, like high pH and ineffective chlorine, which can lead to algae. So it’s often worth addressing high alkalinity levels before they can cause more trouble.

What happens if alkalinity is high?

High alkalinity means your pool water is buffering too much and possibly diluting the effectiveness of chlorine to the point it is unable to sanitize some contaminants in your pool or hot tub. Lowering total alkalinity is a two-step process. The first step is to lower pH by adding muriatic acid.
