Liquid oxygen – what is it and how does it work in the pool?

Maintaining clean, safe, and clear pool water is one of the biggest challenges for any garden or home pool owner. More and more people are looking for an alternative to traditional chlorine disinfection – an effective, but often cumbersome, solution. This is where liquid oxygen , also known as active oxygen , comes in .

In this article, we explain what liquid oxygen is, how it works in the pool, how to use it , its advantages and limitations, and when it's best suited. You'll also find practical advice , mistakes to avoid, and purchasing tips.

What is liquid oxygen (active oxygen)?

Liquid pool oxygen is a modern, chlorine-free water disinfectant. Its action is based on active oxygen compounds (most often peroxides), which, upon contact with water, release oxygen molecules with a strong oxidizing effect.

Thanks to this:

• bacteria, viruses and algae are destroyed,

• organic pollutants are decomposed,

• the water remains clear and safe for the skin.

Active oxygen is especially recommended for people who:

• do not tolerate chlorine well,

• have children or allergy sufferers at home,

• use the pool recreationally,

• they appreciate the lack of odor and the comfort of bathing.

How does liquid oxygen work in a pool?

Active oxygen's mechanism of action differs from that of chlorine. Instead of a long-term residual effect, oxygen acts quickly and intensively .

Disinfection process step by step:

1. When added to water, the oxygen in the liquid breaks down, releasing active oxygen molecules.

2. Oxygen oxidizes microorganisms and organic pollutants.

3. The decomposition products are neutral and safe.

4. The water becomes clean, odorless and irritation-free.

Important: active oxygen does not stay in the water for long , so it requires regular dosing.

Liquid Oxygen vs. Chlorine – A Comparison

➡️ Conclusion: liquid oxygen is a great alternative for people who value comfort, but requires greater control of water parameters.

How to use liquid oxygen in the pool?

1. Checking water parameters

Before using liquid oxygen, check:

• Water pH – ideal: 7.0–7.4

• alkalinity (TA) – stabilizes pH

👉 If the pH is out of range, use pH regulating agents 

2. Dosage

Standard dosage (always check product label):

• first dosage: larger starting dose,

• maintenance dose: every 5–7 days,

• after intensive use of the pool – corrective dose.

3. Filtration

After adding oxygen:

• run the filter pump for a few hours,

• ensure good water mixing.

How often should I add liquid oxygen?

The frequency depends on:

• water temperature,

• number of bathers,

• exposure to the sun,

• type of pool.

Practical tip:

• every 5–7 days with normal use,

• more often in hot weather or under heavy load.

The most common mistakes when using active oxygen

1. No pH control.

2. Too infrequent dosing.

3. No filtration.

4. Use of oxygen in highly polluted water without coagulant.

👉 If the water is cloudy, it is worth using a coagulant
