envii Sludge Klear Pond Sludge Remover, Natural Bacteria Sludge Buster Digests & Controls Organic Waste, Safe for All Fish & Wildlife Treats Up To 60,000 Litres (13,200 Gallons)

wORKS WELL TO CLEAR POND HAE BOUGHT A FEW TIMES NOW. hIGHLY RECOMMEND.

Product seems very good delivery took a long time

Worked brilliantly. Pond before was basically black. Now it is clear! Awesome. First 2 photos are before. Last 2 photos are after.

At first you will wonder if you wasted your money, but this product does work. I started my application 6 weeks ago & only just started seeing the results.

Perfectly happy to use this product and the fish are extemely grateful too. :-)

We have a 2,800 litre pond which is stocked with goldfish. It has never been emptied since we filled it 7 years ago! We now have a small in-pond filter with UV and this has killed off a lot of algae, making the pond water somewhat clearer. We use Sludge Klear to lift dead leaves and remove dead algae. It clumps together the algae in large ‘bergs’, also bringing semi rotted leaves to the surface. You can then lift these off with a fine mesh net (which dead algae doesn’t fall through if you remove it carefully). Initially the water is cloudier but after a few days (and remival of a few bergs, the water clears a bit. We are doing this weekly at present, in the expectation that the water will gradually clear. This is not a product that achieves a fast result but neither does it damage fish (or any other creature’s) health.

pretty sure it worked but then the pond filters kept getting blocked so wether it actually broke down the sludge is hard to tell

This awful stuff has killed my lovely goldfish within a couple of days of putting it into my pond. I spoke to my local Aquatic shopkeeper and it seems the sludge remover also removes hugh amounts of oxygen from the water, and the shock of this can easily kill your fish. I'm so upset. I've had the fish for years and now I've killed them thinking I was doing the best for them by using this horrible product.
