I just received my packages of Azolla & Duckweed mix. The very second that my husband saw them, he said " Surely you are not going to put that stuff into the pond, are you? It will all go into the skimmer, then pump etc." So now has anyone any ideas of how to prevent this from happening!! Our pond is in full sun & I thought this was a GOOD idea! We have several waterlilies that are sending their pads to the surface of the water and one has 2 blooms on it. We also have parrotts feather on the surface. our pond is 14' x 21' with a waterfall & stream.
