## Description

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. TRUSTED BY PROFESSIONALS AND ANGLERS Whether you are a commercial salmon producer, a sport fishery manager, or a dedicated koi enthusiast, Virkon Aquatic provides a documented trail of biosecurity. It is fragrance-free, non-irritating to skin upon dilution, and effective even at low water temperatures. Protect your aquatic investment with the world’s most proven veterinary disinfectant technology, designed to stop disease transmission before it starts. Directions Add one Virkon Aquatic tablet to every 500ml of water. Full directions for use on tub

## Questions & Answers

**Q: Can they be used in a pond which has Golden Orfe in it.**
A: There is no reason not to use VIRKON AQUATIC with Golden Orfe however like all other species it is important to follow the written instructions of our vet.

**Q: Can you use this in low temperature like in the winter**
A: I only add to my pond in spring and summer when water temperature has risen at one tablet per thousand gallons.

**Q: How many tablets for a 900l pond and are they sturgeon safe?**
A: Hi Richard sorry for the late reply. We use a ratio of 1 tablet per 1000 gallons. We have one sturgeon and it doesn’t seem to have any impact on him. We have been using this product in our koi pond for many years and have always been happy with it. We also use malachite and formulin. Blanket answer to keep the blanket weed at bay. Hope this helps.

**Q: how many tubs do you get?**
A: You need to know the capacity of your pond.  1 tablet weekly serves 1,000 galls., and there are 50 in a (my) tub.  Don't buy too many at once because they do have a 'use by' date.
