Our boat slip, along with our neighbors dock, were completely overgrown with duckweed last summer. After a friend had recommended Waterline Preservation & Management we made the call. Within 3 days they had the entire cove we live on completely clear and free of all the grass that was killing our outboards. We all love this guy and have him coming back regularly to service our cove every 4-6 months to keep things in check.
