WinterKleen Fall & Winter Bacteria for Ponds | Koi Pond Winterizer, Leaf Digester, Natural Cleaner - Powerful Concentrated Enzymes and Microbes Clean Pond Water

I like how easy to use this is. I have noticed a little bit of a difference in the weirdness in the bottom of my pond. We’ve been battling algae since the heat of the summertime, and there has been a slight reduction in the funk in our pond since I started using this.

Excellent product! We put in a new pond during the shelter in place, as a family project. By the time it was done, the weather was getting colder. The standard start up bacteria wouldn’t take hold. I got the winter bacteria and right away could see the ammonia levels begin to drop. I continued adding every other day, to jump start the process and after a week or so, had a fully functioning bio filter. Very happy! Will buy more.

Good

I really like this product… it removes stubborn leaves and algae like it said it does!

easy to use, no impact to the fish. just started using so the progress to fully impact has yet to happen. Only issue is I live were its veery windy and the product is light so application timing is important if you want it to fall were you want.

Product works great. I'm using weekly to keep my pond water clear

easy to use it just didn't do anything for my pond

Works great!
