Different Types Of Products

All of the top products used to increase pH in a pool available today are comprised of the same chemical: sodium carbonate. However, while the active ingredient of these products is the same, they differ in size and compatibility with other substances. This section will detail the different forms that sodium carbonate pH-raising products come in. All pool owners have unique, individual needs, so consider which type of product will be right for you.


Pool pH-increasing products are sold by weight and vary greatly as far as how much product you receive. Some options come in the form of small, 2 pound bottles. For personal pools with less water volume, this size may be the right choice. Other manufacturers offer sodium carbonate in bulk, with packages weighing upwards of twenty pounds. For bigger pools, such as public swimming pools, it will make more sense to purchase large amounts of product at one time, both economically and in terms of convenience. Buying more product at once usually ends up being less expensive per pound, and will save time from having to constantly re-order.

The standard dosage for granular sodium carbonate in swimming pools is 1 pound of chemical per 10,000 gallons of water. Gauge the size of your pool to determine what amount of product you will require, as well as how often you will need to re-purchase that chemical.


There are many different chemicals that go into making pool water clean. So, it is important that the chemical you use to fix a low pH in your pool won’t interfere with other cleaning agents. Sanitizers are essential to proper pool maintenance; these products combat bacteria, viruses, and algae that form in your water. The most common pool sanitizer is chlorine, but other chemicals such as biguanide, bromine, and ozone can also be used. Make sure that the product you select to raise the pH in your pool is compatible with the sanitizer that you use.

Some people own a saltwater pool. Many select this type of swimming pool as an alternative to the traditional chlorinated water, which can cause skin or eye irritation for some. If you own a saltwater pool, you will need to find a saltwater compatible pH-increaser. Many popular pool care brands now make all of their products safe for use in saltwater pools, so you will have a variety of options.

The best product to increase the pH of your pool depends on what type of swimming pool you own, including its size, water volume, and the sanitizers you treat it with. Keep all of this information in mind to ensure that you select the right product to properly balance your water.

Buying Guide

Balanced pool water is critical to the maintenance of an enjoyable swimming pool, but many are unsure of exactly how to achieve the ideal pH level in a pool. To start, test your water to determine the current acidic level. The optimal range is 7.2 to 7.8. If your test yields a pH lower than 7.2, your water has become too acidic, and this will trigger undesirable complications. A low pH level will cause discomfort for swimmers in the form of dry, itchy skin and eyes. Also, acidic pool water will break down the pool surfaces and equipment. The pool walls can begin to dissolve, which will contaminate the water and cause discoloration. Low pH levels generally decrease the lifespan of your pool.

To fix a pH level that has dropped too low, you can apply a pH-increasing product to your pool. These products are generally comprised of a dry, granular chemical called sodium carbonate. Read the provided instructions for the product you purchase before attempting to use it. From the test you conducted, you should be able to determine how much product to use. Diluting the chemical is recommended for some products. Follow the given proportion of water to chemical provided on the specific product to ensure precision in the dosage. Avoid adding an excess amount of chemical, as this could cause a pH that is too high. Be careful not to get the chemical on your skin or clothing; try to pour it in when wind levels are low so that you can control exactly where it goes.

Sodium carbonate typically dissolves quickly and does not require manual spreading. Add the chemical to the deep end first, and it is best to pour it in near the water jets. This will ensure proper circulation throughout the pool. Wait a few hours before retesting the water to make sure that the chemical was fully distributed and had time to work. If the pH level is still below the ideal range, start to add more to the pool in small increments.
