How Much Lye Needed for a 22 Ft Pool

Maintaining a pool’s pH balance is crucial for both the longevity of your pool and the comfort of swimmers. While it’s not common to use lye for this purpose, some pool owners prefer it as an alternative to more traditional chemicals. In this blog post, we’ll break down how much lye you need for a 22 ft pool, how it works, and why it’s important to handle it with care.

To adjust the pH of a 22 ft pool, you need approximately 0.2 to 0.3 pounds of lye per 10,000 gallons of water. Be cautious when handling lye as it’s highly caustic. Read on for more detailed steps on how much lye needed for a 22 ft pool to safely use it in your pool.


What is Lye and Why Use It in Pools?

Lye, or sodium hydroxide, is a strong base used to raise the pH of water. In the world of pool maintenance, maintaining a balanced pH (between 7.2 and 7.6) is crucial to ensure the water is safe and comfortable for swimmers. While chemicals like soda ash or baking soda are more common, lye can be used in small, carefully measured amounts to raise pool pH when it dips too low.

Lye is extremely powerful, so using it requires precision. Too much can send your pH skyrocketing, potentially causing skin irritations or damage to the pool surfaces.

Understanding Pool Volume and Chemical Dosage

Before you can calculate how much lye is needed, you need to know the volume of water in your pool. A 22 ft pool, depending on its shape and depth, can hold anywhere from 10,000 to 15,000 gallons of water.

Here’s a quick formula to help you calculate your pool’s volume:

  • For a round pool: Volume(gallons)=π×radius2×averagedepth×7.48Volume (gallons) = \pi \times radius^2 \times average depth \times 7.48Volume(gallons)=π×radius2×averagedepth×7.48
  • For an oval pool: Volume(gallons)=length×width×average depth×6.7Volume (gallons) = \text{length} \times \text{width} \times \text{average depth} \times 6.7Volume(gallons)=length×width×average depth×6.7

For example, a 22 ft round pool with an average depth of 4 ft holds around 11,500 gallons of water.

To raise the pH of pool water, the general rule of thumb is to use around 0.2 to 0.3 pounds of lye per 10,000 gallons of water. Given that most 22 ft pools hold around 11,000 to 15,000 gallons, you’ll need about 0.3 to 0.45 pounds of lye.

However, pool chemistry varies, so it’s important to test the water’s pH before adding lye. You should aim for a pH level between 7.2 and 7.6. Here’s how to add lye safely:

  1. Test the pH Level:
    Use a reliable pool testing kit to determine your pool’s current pH level.
  2. Calculate the Lye Dosage:
    Based on the pool’s volume and your current pH, calculate how much lye you need. For example, if your 22 ft pool has a pH of 7.0, you may need the full 0.45 pounds of lye to raise it.
  3. Dissolve the Lye in Water:
    Always dissolve lye in a bucket of water before adding it to the pool. Never pour it directly into the pool, as it can damage surfaces.
  4. Add Lye Slowly:
    Pour the lye solution around the pool perimeter while the pump is running to ensure even distribution.
  5. Recheck the pH Level:
    After several hours, retest the water to make sure the pH is within the safe range.

Each pool’s water chemistry can vary, so keep adjusting in small increments rather than adding too much at once.

Why You Should Be Cautious When Using Lye

Lye is a strong alkaline chemical and can be dangerous if mishandled. Here are a few important precautions:

  • Wear protective gear: Always wear gloves and goggles when handling lye.
  • Never add water to lye: Always add lye to water, not the other way around, to avoid dangerous reactions.
  • Store carefully: Keep lye in a sealed container, away from children and pets.
  • Avoid overuse: Using too much lye can make the water unsafe and damage pool surfaces.

Signs You May Need Lye in Your Pool

  1. Low pH Levels:
    If your pool’s pH drops below 7.2, swimmers may experience skin or eye irritation. Your pool may also start to corrode, affecting equipment like ladders and pumps.
  2. Water Feels Too Acidic:
    If the water feels too harsh or leaves an itchy sensation, it might be too acidic. This is a good indicator that the pH is too low.
  3. Metal Corrosion:
    Low pH levels can cause metal parts in your pool to rust or corrode faster than usual. Adding a small amount of lye can help counteract this.

How to Handle Lye Safely

Lye is a caustic substance, so safety should be a priority. Here’s a breakdown of how to handle it without risk:

  • Wear proper safety gear: Gloves, goggles, and long sleeves can protect you from splashes.
  • Mix in a ventilated area: Always mix lye outdoors or in a well-ventilated space to avoid inhaling any fumes.
  • Never mix lye with other chemicals: Lye can have violent reactions when mixed with certain substances, especially acids.

Alternative Methods to Raise Pool pH

If you’re wary of using lye, there are alternative methods to raise pool pH safely:

  • Sodium Carbonate (Soda Ash): A more common method to increase pH without the caustic effects of lye.
  • Sodium Bicarbonate (Baking Soda): While more commonly used to raise alkalinity, baking soda can also increase pH in larger quantities.

Both of these alternatives are less aggressive than lye and easier for beginners to use.


FAQs About How Much Lye Needed for a 22 Ft Pool

How much lye needed for a 22 ft pool?
To answer the question of how much lye is needed for a 22 ft pool, the answer depends on the pool’s volume and current pH level. Typically, you’ll need about 0.3 to 0.45 pounds of lye for a 22 ft pool that holds 10,000 to 15,000 gallons of water.

How to figure out the cost per page printing?
To respond to the question of how to figure out the cost per page printing, you’ll need to calculate the total cost of materials, including paper, ink, and maintenance, then divide that by the number of pages printed.

How to save on printing costs?
In response to the question of how to save on printing costs, you can reduce costs by using energy-efficient printers, buying ink in bulk, and printing double-sided whenever possible.
