Product Description

Fast Non-Chlorine Shock for Fresher Pool Water

Zodiac OxyFresh is a non-chlorine shock treatment and oxidiser for swimming pools. It helps eliminate organic contaminants and chlorine odours, supporting fresher pool water without increasing free chlorine levels.

Powered by potassium peroxy-monosulphate, OxyFresh provides fast oxidation support for pools that need a quick refresh. It is ideal for ionised pools, 100% soluble, and allows swimming to resume 15 minutes after application.

Features & Benefits

Non-chlorine oxidation: Helps refresh pool water without adding chlorine to the pool.
Odour control: Helps reduce chlorine odours caused by combined chlorine and organic contaminants.
Ideal for ionised pools: Provides shock treatment support without increasing the free chlorine residual.
Fast swim return: Swimming can resume 15 minutes after application.
100% soluble formula: Dissolves fully and leaves no residue in the pool water.
Built-in water softener: Supports a more comfortable water feel as part of regular pool oxidation care.

Dosage & Coverage

Initial treatment: 200g per 10,000L
Weekly treatment: 125g per 10,000L

Important Usage Information

Test and balance pool water before dosing, including free chlorine, combined chlorine, pH and Total Alkalinity.
OxyFresh can show a false high total chlorine reading for up to 48 hours after application.
Potassium peroxy-monosulphate has a low pH of approximately 2.3, so regular or heavy dosing can lower pH and Total Alkalinity.
Remove pool covers before oxidising. For indoor pools, open doors and windows to allow oxidised contaminants to vent.
Do not mix with other pool chemicals.

Recommended pool levels: free chlorine 2-4ppm, combined chlorine less than 0.2ppm, pH 7.2-7.8, and Total Alkalinity 80-120ppm for fully tiled, pebble and plaster pools, or 125-150ppm for vinyl and fibreglass pools.

This product is classified as Dangerous Goods. Handle with care, avoid breathing dust, and keep away from combustible or incompatible materials.

A Better Pool Experience Starts with the Right Chemistry

Zodiac pool chemicals support the key parts of everyday water care, from balance and sanitising to algae prevention, clarity, stain control and equipment protection.

Each product has a clear role in helping pool water stay cleaner, more comfortable and easier to manage, so the pool feels ready to enjoy more often.

Frequently Asked Questions

Is OxyFresh the same as chlorine shock?

No. OxyFresh is a non-chlorine shock treatment. It oxidises contaminants without adding chlorine, making it useful when the pool needs freshness and odour control without increasing the free chlorine level.

Why is OxyFresh useful for ionised pools?

Ionised pools often run with lower chlorine levels. OxyFresh provides oxidation support without increasing the free chlorine residual, making it a practical shock option for ionised pool systems.

Why can OxyFresh affect chlorine test readings?

OxyFresh can interfere with some chlorine testing methods and may show a false high total chlorine reading for up to 48 hours after dosing. For clearer results, test and balance chlorine before adding OxyFresh.

Why should pool covers be removed during oxidation?

Oxidation can release contaminants from the water. Removing pool covers and ventilating indoor pool areas helps those oxidised contaminants escape instead of settling back into the pool.

Can OxyFresh lower pH or Total Alkalinity?

Yes. OxyFresh has a low pH, so heavy or repeated dosing can gradually lower pH and Total Alkalinity. Regular water testing helps keep pool balance in the correct range.

When is OxyFresh useful to keep on hand?

OxyFresh is useful after heavy pool use, pool parties, warm weather, or whenever organic load and chlorine odour become noticeable. It gives the pool a quick oxidation boost without raising free chlorine.
