Pond Biologics Sweet Water Mirror Black Pond Dye Toss Packets

GREAT Product

This is my third year using this product and I am VERY happy with the results. Pretty much eliminates algae growing from the pond bottom. MUCH better than trying to eliminate the algae manually. Side benefit is it gives the pond a nice look.

Did Not Work at all

Easy to use, but did not work at all. Threw each bag in lake, there was a black ring around the bag for awhile, then the bag and ring disappeared, and never had any color change in lake. On the other hand, when I use liquid dye, I get good, clearly visible results. So I'm very disappointed and strongly advise against purchasing it.

Bags were open

Bought these for a try because I hate messing with the liquid dye. When I opened the bag the bags inside were broken and when I pulled them out (not knowing they were open) the powder got all over my workbench and the floor! So much for just tossing into the pond where the aerators are!
