Duckweed control By Anonymous 5 20th February 2012

This is astonishingly effective. I followed the intructions religiously and now have a clear, sparkling pond - it's almost unbelievable. I don't have fish but my frogs seem unconcerned about its use.

Duckweed Control QWT 053 By Anonymous 2 7th September 2010

As requested, here are my views on the above product. It does appear to be having an affect on the Duckweed in my pond in that the leaves of the Duckweed appear to be getting smaller, but it has not removed it. It does not appear to be having any other affect on the pond inhabitants. I shall persevere with it until the next summer. Mike Muggridge.
