Causes of high pH in your pool
The first step in balancing your pool’s pH quickly is to understand what’s causing the high levels to occur. There are several common factors that can contribute to the problem, including:Alkaline products
Using certain maintenance products such as chlorine stabilizers or algicides can inadvertently raise the pH level of your water. These products contain high levels of alkaline substances and, as a result, can build up and affect your water’s chemistry.Loss of carbon dioxide
The loss of carbon dioxide in pools and fountains occurs through a process called outgassing. This happens when the water is agitated — such as with swimming. This loss of carbon dioxide can then contribute to higher pH levels in the pool.Mineral-rich water
Adding hard water can also play a role in increasing the pH balance of the pool. This is because hard water naturally contains minerals like calcium and iron. Not only do these minerals affect alkalinity, they can create scaling on surfaces and wear down your pool equipment.Temperature changes
Did you know that heat also affects the chemical composition of your pool water? Heat can accelerate chemical reactions which, in turn, causes water chemistry to fluctuate.Causes of low pH in your pool
Similar to high pH levels, low pH levels can also affect your pool system negatively. Here’s what to watch for when your pool water shows low pH levels:Rainwater
While rainwater may seem harmless, the truth is that it can unexpectedly increase the acidity of your pool water. Significant changes can occur in places that are accustomed to periods of acid rain. Acidic pool water will eventually corrode metal pool equipment and even irritate the skin of anyone swimming. Always be sure to use a test kit following a period of rain to ensure your pool is safe to swim in.Pollen, leaves, and other debris
When pollen, leaves, and other organic material gets in your pool, it will eventually begin to decompose and affect the pH of the water. To avoid algae in your pool and cloudy water, skim your pool regularly, especially during seasons when leaf litter and pollen are highest.Bacteria
Similar to decomposing organic material, bacteria can also cause lower pH levels. As bacteria begins to multiply, the waste it excretes is heavily acidic and will significantly impact your water chemistry.How to fix your pH balance overnight when it's too low
Are your pH levels too low? If you test your water and find that you need to adjust your chemical levels, it’s best to act fast. Below are some approaches for how to raise your pool pH quickly and effectively:Add baking soda
Sodium bicarbonate — aka baking soda — is common in many households, and it’s a sure-fire way to fix your pH overnight. To use this method, first test your pool water to gauge what amount needs to be added. Then, measure out 1.5 pounds of baking soda per 10,000 gallons of water. This can raise the alkalinity by 10 parts per million.Add soda ash
While it’s not as common as baking soda, soda ash (sodium carbonate) is much more potent. For every 10,000 gallons of water, adding 6 ounces of soda ash will increase the pH of your swimming pool by 0.2 units. If you go this route, mix the soda ash inside a plastic bucket first and then distribute it evenly.Use alkaline products
For an even quicker fix, you can find commercial alkaline-increaser products to add to your swimming pool that will rapidly adjust the alkalinity. Simply follow the recommended directions and distribute evenly.Use water aeration
Do you have water fountains or jets in your pool or hot tub? You can also adjust pH levels by increasing the aeration. More oxygen can naturally increase pH levels without affecting alkalinity.How to fix your pH balance overnight when it's too high
Is the pH level too high? Here’s how you can quickly lower your pool’s pH:Add a pH reducer
If you have access to a pool store, you can find commercial pH reducers (like sodium bisulfate) that are both safe and effective to balance out your pool water. For best results, consider using this as your go-to solution and follow the instructions based on the volume of your pool.
