Fortunately, there is a way you can raise your PH without affecting the alkalinity of the water, using aeration. In fact, other than draining , this is the only way to independently raise your pH. Aerating infuses the water with oxygen, removing carbonic acid and raising pH in the process.
Aerators are designed to shoot water into the air and have it land in the pool. As the water moves through the atmosphere, it picks up oxygen along the way and injects it into the pool as it lands.
There are dedicated pool aerators that can be used, but you can also add oxygen to the water through the use of pool water features like deck jets , scuppers , bubblers , and waterfalls. High total alkalinity is a serious water issue that requires a remedy, but the good news is that there IS a remedy. About Us Privacy Policy. Starter Guide. Share on facebook. This acid has the advantage of being easier to handle than muriatic acid. Follow the instructions carefully as different manufacturers have different instructions.
With both of these products, make sure to add them in front of the return jets and wait 4 hours before anyone gets in to ensure that the acid has circulated evenly throughout the water.
If the pH level is too low, add soda ash, also known as sodium carbonate or pH Up. We recommend never adding more than 2 lbs or g of soda ash per 10, gallons of water per treatment. Make sure that the pump is circulating to move the water around and then wait at least an hour before testing again. If the pH is still too low, try adding some more soda ash.
Soda ash may make the pool water a little cloudy at first, but it should become clearer after a day or so. If the alkalinity of the water is too high, i. Add one quart ml of muriatic acid or 2 pounds 0. Let the acid mix in the water for about an hour, then test the water again.
Maintain a water pH of about 7 and keep adding pool acid in small increments until the correct alkalinity level is reached.
When you need to raise the pH, you can add sodium bicarbonate, but only if the total alkalinity of the water is also low. Alkalinity and pH generally rise and fall at the same time. Together, these both contribute to increased levels of calcium. As a pool owner, you either know or will find out in time that the pH and alkalinity are two very important features of your pool.
Fortunately, you can keep these both in balance when you know what to look for. The best alkalinity range for a swimming pool is anywhere between 80 and parts per million ppm. Additionally, the best range in pH is between 7. The bottom line is that when your swimming pool total alkalinity exceeds ppm, you need to begin the process of lowering it.
Although slightly different chemistry, they work to achieve the same thing. Although effective, muriatic acid is stronger than other products and can result in burning of the skin or damage to the pool surfaces if not used with caution. Sodium bisulfate, also known as dry acid or acid salt, is another popular choice for many pool owners. You can find pH Down here. After carefully reading over the instructions on the product label, you can begin to add it to your pool.
First choose your product; muriatic acid or sodium bisulfate then follow the instructions for your choice below. Make sure you have a reliable testing kit for both total alkalinity and pH. You can use either pool water testing strips or a liquid water testing kit. Begin to take readings after 6 hours, then 24 hours, then 48 hours to gauge if there are any small changes over this period and to ensure the chemicals are balanced.
Make sure that both the total alkalinity and pH values are within optimal ranges. If so, your job is done!
