We started our small pond last spring and it was as clear as a bell all summer and then all of a sudden about late December the dreaded blanket seed started appearing, now the poor pond is virtually covered! What is the best way to get rid of it? I don't really want to use chemicals because we have 8 goldfish in it. Does barley straw work as well as i've read? and would it be best to completely empty the pond, get rid of the weed and start again, introducing the straw? I have a one lilly and some marginal plants and the pond is serviced with an ultraviolet filter, pump and fountain
Any suggestions gratefully received!
