Sludge Bomb - for ponds up to 20,000 litres

Ordered this a couple of times now. It does the job quickly and it's a decent price.

Pond due its spring maintenance. Water needed clearing and pond contained a significant amount of sludge. Cleaned filters. Product arrived before estimated delivery date, well packaged. Clear instructions on use. Added directly into pond, perhaps I should have added via pond filter 4 days ago. No noticeable improvement to water clarity and sludge remains. Perhaps i am expecting changes too quickly and such products need time to have an effect.

Ordered this product when we had tried other ways of clearing our dirty pond water, without success. Within two days we noticed a difference, water much clearer and no dirt floating around in the water. When cleaning the pond water filter system, we noticed that the deposits in the box were much finer than usual. Will see how long it lasts, but would buy again.

Did clear some water but not all.

Item did absolutely nothing. I did contact seller and was told to clear sludge it will need a second bomb and it doesn’t clear water Seller said “So the bomb is designed to only clear Sludge it will not clear the water in terms of clarity” Tried to get refund but was too much hassle so gave up

Used this and the Aqua Pure Bomb, by the same company, in my wildlife pond which was in a poor state following this year's hot dry weather and a period of relative neglect due to ill health. It had become smelly, sludgy and overcrowded with vegetation and duckweed. I cleared out much of the excess plants, including the underwater oxygenators, where I could without disturbing too many creatures, but the ph of the water was too acidic to use the biological remedies I had bought to deal with the green water and the sludge. Then I discovered these products - easy to use straightaway. The pond has improved dramatically in a short time, the water is clear, the sludge decreased greatly, the ph of the water is now almost ideal, and as a bonus, the duckweed has almost disappeared. Cannot recommend too highly. ,

Used various other products to try and clear very dirty water with no success. Purchased the sludge bomb and within 2 days could see change after a week the water was almost clear.Its now crystal clear,can recommend this product.

My pond had clear water before i added her sludge bomb but since then the water has turned green and I cannot get it clear so dont know if the sludge has gone as cannot see further than an inch in the water this is after a month
