Get rid of green algae from your pond without using chemicals with this all natural algae treatment, it uses Biotek technology to keep the water clear by depriving the algae of the nutrients that they need to thrive. Safe for fish, plants and wildlife when used as directed. It is the perfect way to keep your pond clean and is an essential part of your still water pond maintenance. Instructions for use: Calculate the volume of your pond (Width x Length x Depth) and convert this to litres (1 cubic meter equals 1,000 litres). You will need to use 10ml of product for every 250 litres of pond water. The ideal method is to take water from the pond, using a watering can if you have one, then add the required product back into the pond in stages by diluting down and then sprinkling over the surface of the pond. Do not simply pour the solution straight from the bottle into the pond. If using the Algae Treatment and the Sludge Remover together, we recommend applying the Algae Treatment first, then the Sludge Remover after 1 week. Alternate both products for the first month or until the pond is clear then use the Algae Treatment monthly to maintain clarity.
