Product description Virkon Aquatic Professional Biosecurity Tablets DEFRA-APPROVED PATHOGEN CONTROL FOR AQUACULTURE AND KOI HEALTH Virkon Aquatic Tablets (50 x 5g) represent the gold standard in professional-grade biosecurity. Originally engineered for the UK aquaculture industry, this broad-spectrum virucidal disinfectant is scientifically formulated to eliminate the most resilient aquatic pathogens. It is a critical line of defense against Koi Herpesvirus (KHV), Infectious Salmon Anaemia (ISA), Spring Viraemia of Carp (SVC), and Aeromonas, ensuring the safety of high-value livestock in ponds, hatcheries, and fisheries. ADVANCED OXYGEN-BASED CHEMISTRY Unlike traditional chlorine or bleach-based treatments that leave toxic residues, Virkon Aquatic utilizes a synergistic blend of organic salts and acids. This powerful oxidative chemistry achieves a 99.9% kill rate against viruses, bacteria, fungi, and moulds without compromising the delicate ecosystem of your pond. The active ingredients decompose rapidly into harmless potassium salts and oxygen, making it an environmentally responsible choice that aligns with modern farm discharge requirements and water quality standards. PRECISION DOSING FOR GEAR AND WATER SYSTEMS Each 5 gram tablet provides a foolproof, pre-measured dose to eliminate the risk of under-dosing or chemical wastage. For Equipment Sterilization: Dissolve 1 tablet per 500ml of water to create a potent 1% solution. Ideal for a 10-minute rapid-soak of nets, waders, boots, and filtration components to prevent cross-contamination between aquatic environments. For Pond Conditioning: Apply at a rate of 1 tablet per 1,000 gallons (approx. 5,000 litres) to significantly reduce waterborne bacterial loads. This specialized formula is safe for sensitive species, including Orfe and Sturgeon, and will not inhibit biological filtration when used at recommended rates.
