The duckweed you sent me is the last stuff that died ..... I'm thinking it's the water here .... I've tried duckweed from about 4 different sources, and none lived longer than a couple of months .... and it doesn't reproduce well either, I've read that it will reproduce by double each dday or two, but I had some outside last summer and it died before it could cover the water in a coolr ..... this is waste fish water, not tap water!
