Pondworx Pond Bacteria - Formulated for Water Features and Safe for Koi (4 Gallon Value Pack)

This bacteria works great. I start using it in the spring and before long, maybe a couple of months all the sludge in the bottom of the pond is just gone. If you want to accelerate the process, I noticed if you add an air hose to the area it works even faster

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.

I used Pond Worx on our two and a half acre east Kansas pond last August 2022 on the recommendation of pond ecology specialist The Oklahoma Pond Lady Amie Robison. As you can see from the before pic algae and blue green algae were out of control. Our shoreline plants were disappearing and with the heat we were worried about a fish kill. Not to mention that our dog likes to get in the pond and BGA can make animals sick or even kill them. Pond Worx was so easy to use. I just put on knee high boots and waded out at different points around the pond and poured it in. Within a month we started seeing improvement and by the end of two months the results were astonishing. The before and after pictures are from the same spot two months apart and you can see how amazing the difference. This spring the product was still going strong with the water showing a degree of clarity we had not seen in years. This allowed our bass, crappie and bluegill to spawn out in deeper water which saved them from heat stress mortality in our hot dry spring (2023). And our aquatic shoreline plants are back and better than ever. After the big initial dose (eight gallons spread over a month and a half) all we have to do now is put in a jug every month or so while the weather is warm (4-5 months a year around here) to keep the biosystem rolling along so it is very cost effective. If farm or lawn fertilizer run off is causing algal bloom sickness in your pond use Pond Worx to naturally restore balance and complexity to your blue space environment.

First off understand what this product is and is not. It is a beneficial bacteria that reduces muck and other extra nutrients in your pond. If you have algae mats at the surface or below, bacteria won't kill the algae, it will compete for the nutrients in the pond. If you have a shallow pond with lots of extra nutrients (lawn fertilizer runoff, grass clippings, leaves, fish, geese) this is a tool to help turn the tide against the nutrients that feed algae and undesireable plants. It is also going to work best if you have an aeration system. I feel that this has greatly helped our 1/2 acre neighborhood pond. In 2 weeks I saw a large improvement in clarity of the water and have continued to physically remove the filamentous algae as much as possible. I can see the bottom of the pond in areas I've never seen bottom before. Neighbors have all commented on the clarity of the water and are impressed with the results. The largemouth bass have shown to be very healthy and have beautiful markings and lateral lines where in years before they have been pale from cloudy/dirty water. Our water temperature has been between 50-65 degrees during the last 4 weeks of treatment. With overnight lows I have shied away from treating with algaecides (chelated copper sulphate). And I know that once I do the copper treatment I will basically kill off all the bacteria and have to reapply in a few days following the copper treatment. I look forward to continued use of the bacteria and hopefully will reduce the need to rely on algaecides the more I reduce the nutrient load. From what I have seen I feel confident that paired with carefully timed algaecide treatment we will have a much cleaner and healthier pond. I will update later in the season and hopefully show the results.

I had neglected my pond for several years and it was getting a bit thick on the bottom with leaves, twigs and muck. I tried some of the expensive bacteria type pellets and they didn't seem to make a big difference. I tried some of this Pondworx, ( 1/2 gallon) to a 1/3 acre pond and it cleared the water over night and began working on the bottom muck. Now there are several other steps I took also around the same time which I will describe. The best investment I made was an aluminum pond rake, the one with the long handle and rope. You must diligently rake and remove physically as much as you can from the pond. Casting the rake can reach out about 20 feet at the most from the shoreline. So go around the entire perimeter of the shore and rake this debris out. I let it dry a bit on the grass in piles then loaded it into a wheelbarrow and dumped in my woods for compost. This is a smelly and back braking job but you don't have to do it all in one afternoon. I found that I have to do it twice a year for best results. I also installed a 1/3 HP pond fountain and I already had a twin aerator wind mill that takes care of the O2 levels in the winter when the fountain is put away for the winter. . BUT I believe that the Pondworx made the Big, Big difference along with all the other measures.
