RE: Duckweed and Java Fern???

["Drummond Howard" <drummondhoward at hotmail_com>]

Duckweed is almost impossible to eradicate, I use a surface extractor on a 
75 gallon tank which sucks everything off the surface, yet if it stops for a 
week I have a major outbreak of duckweed again.  I think the WEED in the 
name says it all!
