Waterlife Sterazin 500ml WL85

Waterlife Sterazin is a fish medicine against parasitic infection that affects the fish gill and body that cause fish to flick for no apparent reason. Typically, such disease is hard to detect as it has no symptoms that are visible to the naked eye.

Besides treating the fish gills and body, this parasiticide will also aid the control of internal parasites such as Round Worm, Thread Worm, and Intestinal Worm.

Treatment Volume

Sterazin 500ml treats up to 2970 litres.


  • In order to destroy the parasites in all stages of their life cycle, you will need to use Sterazin on days 1, 3, 6, 8 and 10.
  • Sterazin may also be used to aid the sterilisation of aquatic plants and is highly biodegradable.
  • Do not use when crustaceans, echinoderms, rays, seawater sharks, pirahna, sturgeon or sterlets and related species are present. In these instances use Waterlife PARAGON.
  • Suitable for seawater, tropical freshwater and coldwater aquaria.
