Not worth it, did not work
We bought this pond treatment for use with a 20‘ x 10‘ man-made pond with a depth of only 7 inches. We followed the instructions exactly and it did not work. We used it several times over the course of two months and it did not help improve water quality at all. We even had our filter running 24 hours a day and it still did not work.

Amazing
I have a small back yard pond, about 550-600 gallons. This is amazing. Within hours there was a remarkable improvement. Every day it’s getting clearer, and it was like pea soup. I’ll treat the pond again in the recommended 1 weeks time. This is something that I’ll never be without. It took a while in getting here, as it was delayed in shipment. So glad I was unable to cancel. When it finally arrived,I said, give it a shot. This is truly amazing. I recommend it highly
