From the first time I contacted Love My Pond they were extremely helpful in making suggestions re my large dam which was completely overgrown with duckweed. Over the following months I continued to ask questions which were promptly answered. Finally after deciding to improve my dam as per previous advice by the Love My Pond team I purchased the Dam it Bundle. So far I have used the Biostim Pellets and connected up the aerators. I have one in its final position and the other in a temporary spot waiting on suitable conditions to move it. It is hard to tell if the pellets are working yet, only time will tell. When the weed has fully dispersed ( now down to about 15% ) I will use the Blue Black Pond Dye.
