Safety of the VirescoAquatic Products

The Viresco™ aquatic products are completely safe for use in fish ponds. The first product was formulated for use on commercial fish farms to improve the growth, health and disease resistance of the fish. Its presence in the water was also shown to improve the healing of any wounds on the fish. Understandably, there is no problem using aquatic Viresco™ where other aquatic life is present, eg newts, frogs, or where pets might drink the pondwater.

One interesting example of the use of Viresco™ Aqua is in a swimming pool at a holiday complex in The Gambia. The owners of the Footsteps Eco-Lodge at Gunjur in that country aim to use environmentally friendly products whenever possible. They wanted an alternative to using chlorine in the swimming pool. In April 2004, a consultant to the Eco-Lodge recommended our Viresco™ Aqua as this alternative. The feedback given to us since is that it has been a complete success. A couple of photographs of the pool are shown on this page. Further information about the Footsteps Eco-Lodge can be obtained from their website

Viresco™ aquatic products have been passed by the UK Pesticide Safety Directorate as ‘not within the scope of pesticide legislation because they work by depriving algae by chelating them or by using some form of physical means’.
