Fernox LP Sterox is a highly effective, non-foaming liquid disinfectant used for treating domestic and commercial stored water systems against harmful bacteria, viruses, algae, and biofilm. Its primary active ingredient is a stabilised aqueous solution of hydrogen peroxide.
Key Features and Benefits
- Broad Spectrum Activity: Highly effective against waterborne pathogens including Legionella pneumophila and Pseudomonas, as well as general bacteria and algae.
- Biofilm Removal: It penetrates and removes biofilm, a common source of persistent contamination in water systems.
- No Neutralisation Required: After disinfection, there is generally no need to flush out or neutralise the system because the product naturally breaks down into water and oxygen, except in drinking water systems where a flush is recommended to remove dislodged biofilms.
- Ease of Use: It can be easily introduced into the system via a feed and expansion tank or directly into the water storage tank.
- Compatibility: It is safe for use with a variety of materials commonly found in water systems (including plastics and metals) and is compatible with other cooling tower chemicals.

Test strips are available for monitoring the in-use hydrogen peroxide concentration, which should be around 100 ppm for Legionellacontrol.
