Evolution Aqua Pure Duo Pack Pond Bomb & Sludge Bomb Pond Clear Water Treatment Pond Sludge Remover - Duo Value Pack Offers Complete Natural Pond Water Treatment for Fish Ponds

This cleared up our algae straight away! Our natural pond is quite big at 30mx15m so I wasn’t sure if the one package of two bombs would work, but it did. Very pleased with this purchase.

This product worked very well in my pond i would recommend it very easy to use

I think this will work, just not patient enough

It does what it says cleans the pond good value for the money ....clear pond and healthy fish it definitely works....

Worked perfectly on my pond earlier this year, so suggested to my neighbour to treat their pond with mixed results. Maybe the wrong time of year to apply?

Our pond water has been clear for many years, but after a spell of hot weather, it became obvious that a build up of sludge was generating a build up of gases, evidenced by eruptions of bubbles. The pond water became murky and there was a build-up of debris floating on the surface from the emissions of decomposing vegetation. This happened over a few short days and culminated in a foul smell. Despite a pump, filter, waterfall and various air stones, the situation was getting worse.Having reviewed the options, I decided to use this combined duo pack product. The reviews suggested patience would be required, but my expectations were exceeded. Having dropped both balls into the pond on a Thursday, the water became noticeably clearer on Sunday. The smell was also diminishing and, by Tuesday, the pond had reverted to its normal clear state and the smell had gone.Very pleased with the result! The pond has evolved over many years to be self sustaining and the fish were ignoring any added food as they had enough natural sources. With that in mind, the sludge has become a major feeder for the bottom feeding tench, so was reluctant to clear out the sludge build up and disrupt the equilibrium in the pond. Therefore, this apparently natural solution seems to have worked perfectly and the fish seem to have suffered no ill effects through the situation.I am not sure how often the balls need to be added going forward and will play it by ear. Will probably buy a back up in a few weeks. In summary, I am very pleased with the results of the treatment and now know exactly what to do if it happens again.

Pond still brown coloured

We’ve had this pond for 30+ years and I can honestly say it has never looked better.I tried this in April because the water was more cloudy than usual and within a week there was a marked improvement. It has stayed crystal clear all summer and I can see the gravel in the bottom which must have been covered by sludge in the past. The fish are happy and eating well. Filter cleaning has become a thing of the past and the waterfall is flowing fast and clear.This will be a staple to our pond every year. So glad I tried it.
