Koiworx Muck Reducer - Treats up to 2,500 gallons for up to 4 Months - Tablets Reduce Muck, Sludge and Organic Build up - Formulated for Ponds and Water Features - Safe for Koi

These are great for keeping muck away. Keeps water clear and good for fish health.

First try I didn’t see a difference in my Koi pond. But the second try I did see a slight difference. When I need to purchase smuck reducer for my pond again, I will try a different product.

Works as intended. Some comment on the tablets but this packaged by weight, not by tablet. Our pond and water feature requires approximately half the bottle for one month. Some muck is unavoidable but is needed for good bacteria growth.

I used the fountain pills in a brand new 15-gallon fountain base. Algae slowly started to grow so I added 5 pills every week. After three months the fountain is covered in algae. The product does not prevent algae and is worthless.

I had a pond that was neglected (thank you work) I have been clearing the muck off and excess plants off of the bottom for a while. I was tossing in a few tablets at a time as I was running the filter. This cleared up my cloudiness. After adding some new fish, is back to it's older healthy self.Word to he wise, don't instant results from these types of products, it takes a regiment of tasks to return a pond to it's glory.

I put these in my rain water collector. It was getting pretty ripe and just using the water to put into a jug and water the plants was a stinky job. I dropped 6 of these into the barrel and within days the smell was gone and I can actually see to the bottom of the barrel now!!

Didn't work

Its been several weeks since I put these tablets in my 2,000 gallon garden pond and so far I've not seen any difference, even with aeration. There is a lot of muck build up and our weather has been insanely hot 100+. Not sure if its the hot weather or the amount of sludge that accounts for not seeing an improvement?

Says that it will help improve water clarity, that is a big ol' nope.

Great product, popped four tablets into my medium sized garden pond and soon noted that the water had begun to become clearer, even though I have not yet added an aerator sprinkler to my pond feature.Two tablets popped into my indoor fountain had a very prompt reaction noted due to the aerator action of the circulating water. Crystal clear describes the overnight result.Definitely a good product.
