## Overview

Pondworx Pond Bacteria is a concentrated, eco-friendly solution designed to rapidly break down muck, sludge, and organic debris in large ponds, koi ponds, and water gardens. Safe for fish, plants, and wildlife, this 4-gallon value pack promotes a balanced aquatic ecosystem and allows immediate recreational use post-application.

## Description

Product description Ornamental water gardens and ponds are enclosed ecosystems, sometimes factors like fish load, uneaten fish food, organics such as leaves, sludge and unwanted debris may disrupt the balance. Leaves, grass clippings, algae, uneaten fish food, fish waste, and decaying plants all contribute to build-up of sludge which is not only unsightly, but unhealthy, as it consumes oxygen. Directions Pour directly from the container in several spots along the shoreline.

Review: Hungry little bacteria - 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
Review: Works, but don't expect miracles. - 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.

### ⭐⭐⭐⭐⭐ Works great and Easy to Use
*by K***G on 26 June 2023*

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.
