pH Increasers — A Buying Guide

Not only will a good pH increaser protect you from diseases, but it will also enhance the appearance of your pool by making it look cleaner. How will you get to know which increaser is perfect for you? Do not fret, as we have compiled a comprehensive buying guide to help you swim peacefully by finding the most suitable pH increaser.

What to Look for in the Perfect pH Increaser?

Consider the following before purchasing a pH increaser:

Material

From sodium carbonate to baking soda, pH increasers are made from a variety of different materials. The most preferred material is sodium ash, as it is risk-free and does not contain any chemicals, making it suitable for all types of water. You should also look for granular forms to save your pool equipment from rust and corrosion.

Ease of use

If you’re looking to use the pH increaser yourself, it must be easy to use. Always examine the back of the packaging to determine if there are step-by-step instructions or not. You should not purchase increasers with no guidelines, as drastically boosting the pH of your pool may be dangerous. You should also look for increasers that work quickly, so that you can go back into the pool quickly.

Multi-purpose

You certainly do not want to limit the pH increaser to your pool. A multi-purpose pH increaser can also make your hot tub germ-free for a relaxing time. Since the optimal pH level for a spa is between 7.2 and 7.8, it can also be used to disinfect water for massage tubs.

Preventing Low pH in Your Pool

To ensure that your skin does not get damaged due to low pH, you must search for information regarding optimal pH levels and ensure that your pool always falls in these levels.

Avoid the use of chlorine tablets and stabilized chlorine, as they’re the most prevalent reason for a continuously low pH level in pools. Since they have a pH level of approximately three, they lower your pool’s pH, making it acidic.

Low pH can also occur during a huge party or simply by having a large number of people in your pool in a short amount of time. The higher the number of people in your pool, the more acidic the pH will be. This is caused by the body fluids of those in the pool.

Acid rain, heavy leaves, and dirt in the pool can all reduce the pH level. Also, make sure not to leave your pool unused for a long period of time, as the carbon dioxide in the air begins to disintegrate the water, lowering its pH.

Signs of a Low pH

If you’re unsure when to use a pH increaser in your pool, don’t panic; we’ve listed some of the signs that you may benefit from an increase in pH in your pool.

  • Your eyes will itch and get red after coming in contact with the pool’s water.
  • The pool liner becomes brittle and starts to break.
  • Metal corrosion and oxidation on ladders, lighting, and heat exchangers.
  • Your skin becomes darker and drier after swimming.
  • The pool’s surface gets damaged, especially around the edges where the water meets the walls.
  • Low pH also attracts bacteria, which will create unsightly green scum.
  • You can use a pH meter to check the pH level and use an increaser if it’s lower than 7.

People Also Asked

How much time will my pH increaser take to work?

pH enhancers and increasers often start working within 20 minutes. Add a tiny quantity of the increaser into your pool, leave the cover off, activate the pumps, and let the water circulate. Test the pH level after 20 minutes. 

What happens if I add too much pH increaser to the pool?

Stinging eyes and itching skin can result from using too much pH increaser.  It can also lead to a rise in scale accumulation, which reduces your pool equipment's longevity. Therefore, the best remedy is to use a pH reducer to decrease the pH level.

What is the ideal pH level for my swimming pool?

The pH level affects how well the chemicals in the pool perform, especially their ability to remove algae. Most pools are designed to range between 7.2 and 8.0. Anything less than 6.5 or above 9.5 can cause health problems.

What are the other ways to increase my pool’s pH level?

There are several methods that you can use to increase the pH level in your swimming pool. Calcium hydroxide is the simplest method, but you can also try other options such as limestone and sodium bicarbonate.

Are pH increasers the same as pH controllers?

No, pH increasers are used to only raise the pH level of water, however pH controllers will adjust the levels even if they’re high.
