How To Lower Alkalinity in a Hot Tub

In hot tubs, alkalinity is measured in terms of pH levels. To lower hot tub alkalinity, you must bring down the pH levels. There are a few ways to do this- you can add acid ( muriatic acid or sulfuric acid) directly to the water. You will do this very slowly and over time, or you can add a chemical reducer ( sodium bisulfate) which will slowly bring down the pH levels over time. Follow these simple steps, and you'll have your hot tub back to its perfect swimming condition in no time!

pH Decreaser to Bring Alkalinity Down

When it comes to hot tub alkalinity, most people don't realize that there are ways to lower the levels without having to add harsh chemicals to the water. One way is by using a pH decreaser. This chemical slowly reduces the pH levels over time and is much safer than adding acid directly to the hot tub. A few different brands of pH decreasers are available on the market, but they all work the same way. Simply follow the instructions on the bottle, and you'll be able to lower hot tub alkalinity in no time!

Dosages for raising and lowering Alkalintiy

If you are wondering what dosages you should use to raise and lower Alkalinity, you can read the instructions on the back of the bottle or click on the chart below to get your FREE charts on what dosages you need to balance your hot tub.  Knowing that lowering your alkalinity is time-consuming and can take up to two weeks to get it down.  It is important to fix as it is the buffer for everything else.

Do not worry about pH Until Alkalinity is in the Range

pH levels are essential in hot tub maintenance, but they should not be worried until alkalinity levels are controlled. Once the hot tub alkalinity is lowered, it is safe to start working on lowering the pH levels. This can be done by using a pH decreaser or adding a small amount of acid to the hot tub water. Be sure to test the pH levels regularly and make necessary adjustments to keep your hot tub in perfect soaking condition!

Bump the pH Back Up

Once you have lowered hot tub alkalinity, bringing the pH levels back up to their normal range is essential. This can be done by using a pH increase or adding a small amount of baking soda to the hot tub water. Be sure to test the pH levels regularly and make necessary adjustments to keep your hot tub in perfect soaking condition!

Lowering hot tub alkalinity is essential in keeping your hot tub water clean and clear. Using a pH decreaser, you can slowly reduce the levels over time until they are between 80-120ppm. Once this is done, raise your pH to 7.6 with pH Increaser. Be sure to test the pH levels regularly and make necessary adjustments to keep your hot tub in perfect soaking condition!
