I've tried various treatments, but this is the best. I double dosed the first application and the pond cleared in 3 days. It's the first time I've seen the bottom of the pond in a year. Thank you Envii sludge clear. Review: It does work, but buy yourself a fine-meshed net! - 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. ## Features - Digests Sludge & Removes Organic Waste – Sludge Klear contains billions of beneficial bacteria and enzymes to help digest sludge, remove organic waste & phosphates in garden ponds. - Reduces Pond Maintenance – By digesting and limiting the sludge in your pond, this will prevent all smells and ensure your fish are healthy.
