Review: Great - Exactly as described, used to dose the koi pond. Cleared it up in 1 dose
Review: Seems to work - After 20 years of keeping pond fish, had some kind of bacterial outbreak this year and lost quite a few fish. Whilst this doesn't treat or save the actual infected fish (I tried), believe it still arrested the problem within the pond and didn't seem to affect other fish or anything else, including the biological cycle. Have used it a couple of times at dose of 2 or 3 grams (half a tablet) per 1000 litres of water. Going forward will use it as a preventative in the Spring as that's when the highest risk occurs.

## 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.

### ⭐⭐⭐⭐⭐ Great
*by B***G on 14 January 2026*

Exactly as described, used to dose the koi pond. Cleared it up in 1 dose

### ⭐⭐⭐⭐⭐ Seems to work
*by F***K on 20 October 2025*

After 20 years of keeping pond fish, had some kind of bacterial outbreak this year and lost quite a few fish. Whilst this doesn't treat or save the actual infected fish (I tried), believe it still arrested the problem within the pond and didn't seem to affect other fish or anything else, including the biological cycle. Have used it a couple of times at dose of 2 or 3 grams (half a tablet) per 1000 litres of water. Going forward will use it as a preventative in the Spring as that's when the highest risk occurs.

### ⭐⭐⭐⭐⭐ Effective Precaution
*by D***D on 23 February 2024*

These tablets can be used in 2 ways: 1) Precautionary measure to reduce the bacterial & viral load on the pond without any discernible effect on the biological media in filters. 2) Disinfection of nets and equipment to prevent cross or re-infection, particularly during and after an outbreak It is relatively simple to use; just put the required dose (which is specified on the pack and online) in a bucket add just boiled water, stir thoroughly, leave to cool (you could add some cold pond water to hasten this cooling) then add evenly over the pond surface. You can repeat this process up to the point mixing and cooling to use as a disinfectant (the dose will be significantly higher and must not be put in the pond at this level), the disinfectant mixture will last at least a couple of days giving ample time to treat all of the required equipment by soaking etc.
