Great product and customer service
Great product. Great company. Fast shipment. It arrived in 2 days. Works as advertised. I used a hand held fertilizer spreader for good coverage.

Pond was clogged with bottom
Pond was clogged with bottom weeds. I waited until pond water went down below outlet (pumped) and added it. Hard to do middle but rest wasn't hard. After 3 days the pond turned a copper color and the weeds were dying. After 2 weeks all are dead. Good stuff!

easy milfoil application
it's slow acting like it says in the instructions. This worked great for clearing out the milfoil around the dock to get the boat in and out along with swimming.
