Muck Reducer - 15LB Natural Sludge Solution Tablets for Ponds & Lakes, Away Muck & Odor Control, Safe for Aquatic Life, Wildlife & Recreation, Treats Up to 90,000 Sq Ft

I was honestly skeptical about these tablets but they actually made a noticeable difference. I tossed a few in the mucky shallow end of my pond and within a couple weeks the water looked clearer and there was way less sludge. The smell also started to fade which was a huge relief. I didn’t have to scoop or stir anything which I really appreciated. The tablets dissolve gradually and I like that they’re safe for fish and turtles since I’ve got both. I’ll definitely keep using this stuff through the warmer months. It’s low effort and high payoff.

Great product - it keeps sludge from accumulating in our large koi ponds and recirculating creek, helping avoid frequent expensive professional cleaning. The packets provide an easy measurement and are convenient to apply to the extensive areas where it's needed.

Works well. More than I expected. Good results

I wasn’t sure about these little tabs but figured I’d give them a go since they are much cheaper than having my pond dredged. I recently bought a house with a farm-type pond that has been neglected for some time. I have used these tablets for nearly a month and I do believe they are helping control to muck along the shore and I have wild fish who don’t seem to be bothered. The water is definitely clearer. I’ll will buy again.

I use this in my pond multiple times and didn’t really notice a difference. I probably will not purchase again.

Definitely seemed to clean up the water in my pond and help with the scent of rotting leaves

It killed my fish. I Never lost even one fish in the 3 years since I built a 2800 gallon pond. After applying a 1/3rd dose, Within couple of weeks of applying this product, all my koi and goldfish died. No other explanation since my water quality is stable and all my water parameters test fine and are validated using a master pond water test kit (KH, GH, PH, nitrates, ammonia, phosphates, and ample aeration). All the dead fish looked sick At time of death. Will never use again. Now I have to drain my pond, refill and start all over and allow pond to cycle to rebuild the water biome before restocking fish. Buyer beware. I suppose the only other explanation is that a bird or other wildlife could have carried a parasite into the pond but it’s awfully suspect that I started losing 2-3 fish a day within a week of applying….

Our pond plants have been overgrown since last summer and blocked water flow. It reduces the effectiveness of our biological filtration systems. We have trimmed the plants back and tried many different Muck and Sludge Remover products in different forms, including liquids, pods, powders, blocks and tablets. Compare with all those solutions, tablets have advantages of easier to apply to every designated spots in the pond and financially more economical. This pellets are small and you can just throw them into the pond evenly from everywhere. It took a little more than a hour to dissolve. At first, we followed the recommendations of 2500 gallons dosage rate and applied 100 tablets twice a week. Making sure it is safe for my koi, two weeks later we doubled the dosage to enhance the effectiveness before winter comes. It describes this product can “reduce up to 2 inches of pond muck per month”. After 2 months of using, we are unable to measure how much muck and sludge has been removed. But definitely notice the improvement of clarity and less dirty of filters. Looks at before and after pictures, you can see how great the result is.
