Having a problem with duck weed in my smallish garden pond and sick of constantly skimming, I bought Blagdon's Duckweed Buster. I calculated the volume of pond and mixed the appropriate dose with pond water and using a clean watering can treated the surface of the pond. That was last saturday...
I've been trying to get this stuff everywhere. I've been laughed at and mocked in shops. " Duckweed? do you mean duckweed killer?
Anyone have any spare? or any online shops i can get some from?
