How to Add Borax to the Pool? a Complete Guide

Learn how borax can help your pool’s annoying pH problems and prevent the growth of algae, leaving the pool sparkling and feeling soft.

Borax is excellent for your pool, as you may not know. Its chemical properties aid in stabilizing pH at a desired level and allow you to use less chlorine because of the boron it contains, which inhibits the growth of algae. It does, however, require some knowledge of chemistry to be used effectively to buffer pH and stabilize alkalinity.

To learn more about using borax in your pool, read this guide.

How to Add Borax to Your Pool?

You must increase the pH of your pool water if it is too low. A simple and effective way to do that is to use borax. All you need is a pH testing kit, borax, and safety gloves; just follow these instructions after that.

Step 1: Conduct a PH Test

Verify the levels of acidity in the pool water as the first step. Find the pool’s capacity and current total alkalinity to calculate the amount of alkalinity needed to raise the pH.

Step 2: Determine the Amount of Borax to Add

Determine the quantity of borax you should add to your pool using my borax pool calculator. What primarily determines this is the chemical makeup of your water. For every 5,000 gallons of pool water, I advise adding 20 ounces of borax. This amount will help increase the pH by approximately 0.5.

Step 3: Add Borax to Your Pool

Water pumps and filters for your pool should be turned on and left to operate. After adding borax to the skimmer, run the pump continuously for 24 hours.

Step 4: Re-check the PH Levels

It’s time to check your pH levels to see if you have reached the ideal range after the 24-hour period has passed. It may still be low, as you discover. Don’t freak out; depending on the new pH level, add more borax equal to or slightly less than previous measurements.

It’s important to keep in mind that if the pH level of your pool water is off by 0.2 or less, you shouldn’t be alarmed. This will naturally lessen over a few weeks.

Benefits of Using Borax in the Pool

Borax is tremendously effective at stabilizing alkalinity and acting as a pH buffer in swimming pools.

In the past, pool owners have relied on baking soda (sodium bicarbonate) and soda ash (sodium carbonate) to keep the pH levels in their pools in check, but these chemicals have drawbacks.

They do increase pH levels, but they also increase the water’s overall alkalinity. Adding chemicals to stabilize the water is defeated by increased alkalinity because it causes the pH level to fluctuate.

Borax, in contrast to carbonate compounds, stabilizes the pH without boosting the water’s overall alkalinity. Preserving the pH at a constant level also prevents the growth of algae while enabling chlorine to sanitize the water effectively.

Borax does not evaporate once it has been dissolved; it stays in the water forever. With less time to form chloramine, this guarantees swimming in sparkling, soft water. There will be greater savings because you’ll use less chlorine.

When Do You Need to Add Borax to Your Pool?

Borax doesn’t rot, lose its potency, or expire. The only things that can lower it are leaks or draining, filter backwashing, drag-out, splash-out, and water loss.

As a result, you only need to add it once, and unless your pool is losing a lot of water, you won’t need to add it again until you drain and refill the pool.

How Much Borax to Add to Your Pool?

A pH test can help you determine how much borax to add to your pool. If the pH level is below the desirable range of 7.2–7.6, you must raise it.

For every 5,000 gallons of water in your pool, add 20 ounces of borax (this is only a rough estimate because your pool may need a different amount depending on different chemical factors).

The Importance of PH in Swimming Pools

To ensure an enjoyable, risk-free day in the water, the pH levels of a swimming pool must always be in balance. Although 7.2 to 7.6 is a good range, pH 7.4 is recommended for swimming pool water.

Attempting to swim in a pool with a pH level below 7 would be an uncomfortable excursion. Acidic water will cause redness, irritation, and itching in the eyes and on the skin. As a result of the acidic water harming your mosaic tiles and encouraging algae growth, your pool would also suffer as a result.

Your pool’s water will be cloudy and murky when the pH level is higher than 7, and it could clog filters and pipes. This alkaline water will irritate your eyes and lessen the benefits of chlorine, requiring you to use more of it and costing you more money.)

Conclusion: Add Borax to Pool

It can be difficult to maintain the proper water chemistry in your swimming pool. Borax can help with that.

Borax can be added on its own if you’re using it to increase the pH of the pool water. Borax may need to be added along with an acid to balance the pH if, on the other hand, your pH is fine but you want to add more alkalinity to buffer it.


Where Do I Add Borax in Pool?

Turn on the water pump and filter for your pool and let them run. Add borax to the skimmer and leave the pump to run for 24 hours.

Can You Add Too Much Borax to Pool?

If you have an excessive amount of borate, drain and replace 1/3 to 1/4 of your pool water with a pH increaser. If pH and TA become out of balance, you can lower them both with muriatic acid.

Do You Add Hot Or Cold Water to Borax?

Using warm water helps the stains can be more easily removed with borax. Just keep in mind that the more Borax you add, the more water and/or clothes you use. For each gallon of water, you used to fill the bucket, add ½ cup of borax. Borax needs to be gently mixed into the water to dissolve it.
