You may be familiar with some chemicals that pool water contains, and one of them is alkaline. In short, alkalinity is the term that we use to refer to the measurement of how much acidity that it can neutralize.

How to Lower Alkalinity in Pool | Simple Tutorial

Test the Alkalinity Range

TA (total alkalinity) of a residential pool should be between 80 to 120 ppm, if it’s higher than 120 ppm then you need to lower it. To find out the level of alkalinity of your pool water, you can follow these steps:

Prepare this tool:

  • Pool water testing kit with alkalinity reagents

Follow these steps:

  • You can first identify the high level of alkalinity by some visible signs like the murky water, cloudiness and calcium scaling that clogged the filter.
  • If the cases happen, then you need to test the alkalinity by using the kit.
  • Typically, you will need to add the pool water to the tube then add the reagents, then follow the manufacturer’s instruction to check the alkalinity level.

Calculate Pool Capacity

Before start lowering the alkalinity of your pool water, you need to know the water capacity of your swimming pool. It will determine the amount of muriatic acid which will be the main material for the lowering process.

  • If you build your swimming pool under your authorization, then you may have known its volume.
  • If not, today you can find a lot of websites that offer the manual pool calculator, you can use them for this step. Remember, you have to at least know the length, width, diameter, and depth of the pool to calculate the pool capacity.

Prepare the Acid

To lower the alkalinity of pool water, we’re going to use muriatic acid. This kind of substance can harm your eyes and skin, so make sure you wear some safety gear.

Prepare these materials:

  • Muriatic acid

Prepare these tools:

  • Eye goggles
  • Rubber gloves

Follow these steps:

  • Switch off the pool circulation pump.
  • Wait for about an hour to ensure that the water has stopped moving.
  • Wear safety gear.
  • Read the manufacturer’s direction to amount the muriatic acid that you need for your pool volume. The rule of thumb is 1 quart of muriatic acid is sufficient enough for 10’000 gallons of water.

Dilute the Acid

Once you have measured the acid, you need to dilute it with water instead of pouring directly to the pool. Keep wearing your gloves and goggles.

Prepare these tools:

  • 1-gallon bucket
  • Some kind of stick made of wood or plastic to stir the solution

Follow these steps:

  • Add 1 gallon of water to the bucket first.
  • Then, add muriatic acid to the water and dilute them completely.
  • Remember to always add the acid into the water, not the other way around. It’s important for your safety.
  • Pour the acid into the deepest part of your swimming pool all at once. Do not pour it around the pool.
  • Let the acid solution to sit for about an hour in the water.
  • Turn on the circulation pump and wait for about 6 hours before you retest the alkalinity level.

Recheck the Level

The last step is to recheck the alkalinity level of your swimming pool. Though it’s the last step, you may need to keep rechecking until you get the ideal range of alkalinity. Lowering the level of alkalinity is a slow process so you have to be extra patient.

  • If you find that the level of alkalinity is still lower than the ideal range, you can add more muriatic acid, but you have to wait for 2 to 3 days before adding it.
  • If you find that the pH level of the pool is lower than 7 ppm, you need to give more aerators as an addition to the pool’s pump. The unstable alkalinity level also affects the pH level of the pool.
