Review: Works if you use it as instructed - So duckweed is an absolute pain and just seems to multiply no matter what. Thought I’d try this and it really works if you use it properly. As others have pointed out, that means getting rid of as much duck weed as possible (I certainly got most of it, but not all the stuff buried in the pond plants). Yes, that’s a pain to do with a net and bucket, but essential. Despite the on-pack suggestion to repeat after 7 days, my first dose has left the pond completely free of the duckweed after 3 weeks, so for once I’m impressed with a Blagdon product.
Review: Didn’t work for me - Doesn’t work!!
