PondWorx Pond Bacteria - Formulated for Large Ponds, Water Features and Safe for Koi - Gallon

This stuff is amazing. I ordered it to use in my water butts. I had to configure how much was to be used for each of the butts. Treated one day and 24 hours later the rain water was usable and didn't smell anymore. The water had cleared so nice. Bonus it doesn't harm your fish if you happen to treat a pond. That's something I read while deciding to order. Brilliant stuff!!

I have a small back yard pond, about 550-600 gallons. This is amazing. Within hours there was a remarkable improvement. Every day it’s getting clearer, and it was like pea soup. I’ll treat the pond again in the recommended 1 weeks time. This is something that I’ll never be without. It took a while in getting here, as it was delayed in shipment. So glad I was unable to cancel. When it finally arrived,I said, give it a shot. This is truly amazing. I recommend it highly

It works but I can not honestly tell you how well. Our pond had a massive algae outbreak and after using an algae control product, we had a lot of muck on the surface and on the bottom of the pond. We put in one gallon a week for 4 weeks and saw a change in the ponds health. It did not harm the large mouth Bass, tilapia or bait fish. I purchased it again to continue the cleanup. One thing it does mention. Algae control products can effect the bacteria so don't use them at the same time.

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!

Slow working.

Used the Pond Bactria and Water Clear along with a pond aerator. The results are amazing after only a few weeks.

This is a great product for small ponds.

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 ..
