Best product for small pond maintenance. I don't know how it would work on a large scale pond; mine is about 2000 gallons (12 x 20 x 1 1/2 ft deep).

Sludge Away does what it is supposed to do - removes muck and sludge. We use it every spring in our 2000 gallon water garden because it does break down organic materials that collect over late fall and winter in just a couple of applications. Product is also very easy to use.

Works very well but must be patient not instant fix. I have been using this product for 10 years and I highly recommend it. Clears water giving it a crystal clear appearance.5 feet deep and I see the rocks in the bottom clearly.

This is the 1st time I've used this product. It replaces another product I used for years that is no long available. It is being sold to members of a local pond club I used to belong to a long time ago, so I figured it must be good. Reviews were favorable, too. Anyway, delivery was right on time. Just follow the instructions adding the proper amount to the water. My pond is 450+ gal so I measure & round up to 500g. It clearly states that it will "discolor" your pond water, but it will clear up in a few days. A lot of people complain about this discoloration, but it's part of the process. My water was clear to begin with, but over the winter I accumulate algae + the sludge from breakdown of debris. After turning off my pond pump & letting the water settle, I mixed the product in a small bucket filled with the pond water, stirred, & poured around the perimeter. It looked as if I poured food dye into the water -- it became totally 'brown', but still with some clarity. After awhile I turned the pump back on & walked away. Surprisingly, my pond cleared up within 24 hrs. Yes, I can still see algae & sludge, but it's slowly breaking it down. I still have a few more applications before the Spring treatment is complete, but it appears to be working as advertised. My fish seem happy & unaffected. Keep in mind, you'll be cleaning out your skimmer more frequently when applying this.Read full review

I used this stuff 3 weeks ago and did everything what the discription told me. My pond look worst than before this stuff makes your pond water dark after 3 weeks my water still didn't chance. I am not satisfied about this product!
