Everything worked fone
Pleased with your service and the product ordered. Very good service.
Every year we get mat algae that starts in February. I have found that this product, which I apply at low levels, knocks back the algae before it gets started. This particular size is excellent for distribution where I need it to go. I walk the bank of the pond and put it in the areas algae is growing. I applied the product and within 24-48 hours I saw a notable difference. As the temperature warms I may need to hit spots, but the initial application was exactly what I expected. We really don't see excessive algae other than around the perimeter, but I may treat areas in the interior pond if we have an outbreak. I'll order it again. Very quick shipping too.
Product received quickly.
