Justin Knox –
I’ve used Algae Stopperz for three seasons now and have seen a significant reduction in green algae. The pellets sink well and don’t disturb the water surface. I place them around the edges and repeat every two months. My pond looks much cleaner and the fish seem more active.
Peter Bell –
It took about three weeks to see results, but after that, the algae growth slowed down noticeably. I added them in autumn and winter, which helped prevent spring blooms. Works well with my existing pond plants.

As a natural solution, I appreciate that there are no chemicals involved. The pellets are easy to distribute and don’t float. I’ve noticed fewer blanket weeds, especially in the corners of the pond.
