Used Algaefix in my koi pond after a summer spike in green water. The water cleared up within a few days and my fish seem more active. No visible harm to the fish or plants. Good product for regular maintenance.

It works well for string algae and green water. Applied every two weeks and noticed a significant improvement in water clarity. A bit expensive but effective for a small pond.

My pond had blanketweed growing fast. After one application, the growth slowed and the water became clearer. Safe for fish and plants. Would recommend to anyone with a similar issue.
