Pondworx Pond Bacteria - Concentrated & Formulated for Large Ponds, Water Features - Safe for Koi - 32ounes & Treats up to a Quarter Acre Pond

For a while I used another pond bacteria that was super expensive and not nearly as effective as this stuff. I had an algae bloom in my pond. Since I have started using this once a month in my 2 acre pond, it has not bloomed again! It is also very easy to use. It helps with smelly decay odors, too. I have a lot of ducks and geese that "share" their nitrogen, i.e. poop, so the nitrogen load is an ongoing issue. This product seems to handle that challenge with ease. I am very happy I found this, and such a good price compared to some other stuff out there!

The next day I saw a difference. The water was clearer. Will continue to use to see more results. I used two gallons as I have a large pond (55,000 gallons).

Not sure on this product, seams to help in one application but believe this requires multiple applications to work properly ! Unsure still on this product noticed the foaming on the pond surface . Used with pond dye to help with algae on my small farm pond ..

This stuff is awesome! We noticed a definite difference in the algae overgrowth in our 1/3 pond within a couple days. I would highly recommend this product.

Works great to clear the water but be very careful how much to add if you have goldfish they don’t like this stuff

Absolutely works! I have an acre of straight pond and saw improvement 3 days max! No measurements, no fuss! 🥰

DO NOT PURCHASE!! Instead of cleaning my small pond, it makes it more cloudy and the bacteria grow so fast even with the constant aeration and filtering! Also, you can’t return it or get a refund so I would be safe and just don’t buy it.

Nice product. It’s working. It hasn’t been a week & my pond is clearing up already.
