How to low pH level

2021-04-15


Before doing anything, always test your water first. Use a pool test kit to check the pH, acid demand, and total alkalinity.

Once you`ve determined that the pH level is too high, you should now work to restore the balance. There are two main products for lowering the pH. These are sodium bisulfate (also known as dry acid) and muriatic acid.

Here are the steps for each product:

Sodium Bisulfate

1. Read the manufacturer`s instructions and measure the correct amount based on your initial testing. Some suggest adding ¾ of what`s recommended to allow for easier correction.

2. Sodium bisulfate usually comes in powder form. Avoid using it on a windy day to avoid blowback to your skin and clothes.

3. Add the chemical by getting down to the water as close as you can and downwind from you if it`s windy. Apply it over the water return jet site to facilitate spreading the powder throughout the pool.

4. The powder should dissolve on its own after ten to fifteen minutes.

5. Wait at least six hours for retesting but make sure to do your test within 24 hours.


Muriatic Acid

1. Muriatic acid is a powerful corrosive so make sure you`re wearing protective gear, such as gloves and goggles.

2. Again, read the instructions and measure the amount accordingly.

3. There are two ways to add muriatic acid to your pool. The first is to turn off the pump and then pour a slow, steady stream at the deep end. Allow the acid to settle at the bottom of the pool, then turn the pump back on to circulate it.

4. The second method involves pouring it over the return jets and letting the pump do its work.

5. Retest the water after six hours but don`t wait for more than 24 hours.
