Waterlife Sterazin 250ml



Waterlife Sterazin helps to control parasite disease (on fish gill and body) which cause fish to flick when no disease symptoms 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.

Sterazin 250ml treats up to 500 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.
