Did the job - no casualties no effects to rest of pond

Good productWorked on the fish with no problemsEasy to useValue for Money

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

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.

Measuring system didn’t work as the fluid just ran out the bottom of measurement cup. No valve in the bottom.

My fish had started to look unwell with a cut to its side.This Blagdon remedy was easy to use by diluting the stated amount based on the size of the pond into a bucket of pond water and tipping it back into the pond.Repeating this each day for a week, as stated on the instructions, I was pleased to see it make a full recovery about 2 weeks later.I still have enough left in the bottle to repeat the process if any other issues happen, but all is good with a few months now passed.Happy to recommend this product.

Minnows all had white fluffy growths. Followed instructions and added this to water for three days and totally cured problem. Hasnt returned after 6 mths now so very pleased.

Just as advertised and quick service
