Blagdon Fast Acting Anti-Fungus & Bacteria Water Treatment for All Pond Fish, Finrot, Mouthrot, External Bacterial Infections, Wildlife & Fish Safe, 1 Litre

I was sceptical having tried many other fixes for blanketed over the years but this actually worked. I have to re-dose about every 8 months but it clears the weed in a couple of days.

You can tell where it has gone as it turned the water a nice green colour

Bought this as my pond went green after my pump failed and the water stayed green even after buying a new pump. Instructions are very easy to follow and very easy to use, just calculate your pond water in gallons and squeeze the amount you need to the top and pour it into your pond ( I added mine to a jug of water first just so it diluted it a bit). After a few days the water improved a lot but was still a bit green so I added a bit more and after a few more days the water cleared. Fish now look very happy.

Needed to treat my pond, had a poorly fish, done the five day treatment, fish are all fine now.

Persisted with this but issues just return. Ended up getting proper veterinary stuff that sorted it with a single dose

One of my larger coloured koi had fluffy growths on its fins, saw this and thought better take some action. It's a five day treatment so because of the volume of the main pond I bought a small kids pool as a quarantine tank, about 500 litres, this was more economical than trying to treat the main pond and had the benefit of being able to keep my eye on it better. I would have required about 3 bottles to do the main pond over a five day period and it's not cheap. It worked fine and now back with it's friends in the main pond.

Just as advertised and quick service

Does what it says however 1 big thing I will suggest is when it says add dose over 5 days the calculation that needs to be divided by 5 at the end, ratio of fluid to gallons in your tank then divide by 5 and then add this amount to your pond on day one and so forth to finish the course, I did not do this and my pond went goblin green, could barely see anything but the strong amount cured the problem however the filter didn't get rid of green so had to put up with this for several days u till 20 percent water change and flush through untill got clear water again, however doing it the stated way above solved the problem and was able to not turn the water a horrid green.So in all fairness the multiplication should be explained more in detail on the bottle.Overall good product.
