Viresco Filter-Start 25g
Viresco aquatic products for all your pond needs …
For clean, clear water, healthier fish and more abundant wildlife nothing works as effectively and economically as Viresco. It uses a combination of different micro-organisms that clean water by removing the soluble nutrients on which algae feeds and digest the organic matter that makes ponds cloudy. One application can last many months and as a non-chemical product it is completely harmless to wild birds, fish, frogs, newts, pets, plants, insects and humans.
We also sell Viresco Filter-Start for the introduction of healthy bacteria into new or existing filters. Contains microbes to initiate the breakdown of ammonia to nitrite and then nitrate in pond filters. 25g treats ponds of approx. 9,000 litres (2,000 gallons) of pondwater.
All Viresco products are:
• Non-chemical – totally biological
• Easy to use with a long shelf life
• Long lasting – one application lasts many months
• Harmless to fish, plants and wildlife, even if overdosed
• Full instructions with every pack!

Viresco Filter-Start contains microbes plus support nutrients. It is recommended for use in new filters as well as for maintaining good populations of microbes in established filters.
Rate of use
25g Viresco Filter-Start will treat approximately 9,000 litres (2,000 gallons) of pondwater. To calculate the volume of water in your pond multiply the length in feet by the width by the average depth then multiply by 6.23. This will give volume in gallons. If your pond is round or oval, just “square it off” and use the approximate measurements.
Filter size compared to pond size
It is recommended that the volume of biological filter should be at least 3% of the volume of the pond. However, this can be modified according to the porosity of the media used in the filter. The object when using Viresco Filter-Start is to put the microbes on to and into the material in the filter. This is best done by using a number of applications of the product.
Method of use
Ideally, Viresco Filter-Start should be dissolved in a relatively small quantity of water and left for a few hours before putting directly into the biological filter. About half a litre (approx a pint) of water should be used. Half a level teaspoon (2½g) of Viresco Filter-Start should be used per 1000 gallons of pondwater and then repeated on days 3, 5, 7 and 9. Maintenance doses of half rate applied every 3 to 4 weeks should also be considered.
VIRESCO FILTER-START IS NOT A CHEMICAL. IT IS A BIOLOGICAL PRODUCT CONTAINING MICRO-ORGANISMS.
VIRESCO FILTER-START IS HARMLESS TO FISH, PETS, BIRDS, PEOPLE AND PLANTS.
