Active oxygen is highly effective against organic matter such as bacteria, viruses, as well as fungi and algae. It is an ecological disinfectant with limited effects, making it a treatment primarily suitable for small pools, spas, mini-pools, or above-ground pools.

What are the effects of active oxygen and how to use it in your pool?

Active oxygen comes in various forms: tablets, granules, or liquid. It is non-irritating to mucous membranes, skin, and eyes, and emits no odor. The application of active oxygen does not affect pH levels. As a shock treatment, it is capable of sanitizing the water or eliminating algae. When it comes into contact with water, it acts on micro-organisms through oxidation without producing residues like bromine or chlorine. This treatment is compatible with all types of treatments and pool liners. Active oxygen possesses anti-mold and antibacterial properties. However, although it disinfects, its effectiveness does not last long. It is recommended to treat your pool at least once a week, or to invest in a regulator or a dosing pump. This treatment should only be applied at temperatures below 30 °C, as it is sensitive to pH variations.

The Advantages of Active Oxygen:

1. It is effective and powerful against micro-organisms such as algae.
2. Ideal for treating very cloudy water (green/yellow).
3. It is an entirely natural and environmentally friendly product.
4. It emits no odor.
5. It does not cause any irritation to eyes, skin, or mucous membranes.
6. It does not alter the pH.
7. It is compatible with all standard treatments such as chlorine, bromine, UV, and PHMB.
8. It adapts to all types of pool liners.

The Disadvantages of Active Oxygen:

1. Sensitive to UV rays.
2. Sensitive to water temperature.
3. Sensitive to pH that is too low or too high; pH must be maintained between 7 and 7.6.
4. The action time of the treatment is brief because it dissolves quickly.
5. The quantity required for continuous and effective treatment is relatively high.
6. Requires the use of other chemical products (disinfectants, stabilizers, flocculants).
7. Must be handled with care and stored away from air and moisture.
8. Can distort the reading of chlorine levels for a certain time, as chlorine remains present without being detected by test strips.
9. Not suitable for natural pools, which do not use any chemical products.

Manual Dosing

The recommended dose is 6 to 8 cl of liquid oxygen per week for 1 cubic meter of water.

Even when not in use, active oxygen gets consumed on its own. Since its action is not long-lasting, it is imperative to adjust the concentration every week for effective treatment.

6 cl / m3 per week if the temperature is below 25°C.

7 cl / m3 per week if the temperature is above 25°C.

8 cl / m3 per week if the temperature is above 28°C.

For example, for a 30 m3 pool with water at 23°, you would need to add 30 x 6 = 180 cl of active oxygen each week. A 5L drum will treat your pool for approximately 3 weeks.

Finally, it is worth knowing that overdosing on active oxygen does not pose any particular risks for swimmers.
