## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent product!
*by C***S on July 3, 2025*

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 and Easy to Use
*by K***G on June 26, 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.

### ⭐⭐⭐⭐ Decent product, durability and affortability is a concern
*by N***Z on July 13, 2025*

Why did you pick this product vs others?:Product seems to be working Ok but its benefits doesn't last long on my pond. I will continue to use a little longer and see what happens, hopefully I can make it work as an affordable option.Fish health:Fish seems to be happier and more activeDurability:It does not last long on my spring fed pond.
