This has worked on Duck Weed by slowing down it's propagation. Previously I would spend 30 mins ea week removing the duck weed with a net only to have it come back to the same extent the following week. Using this product you still need to physically remove as much duck weed as is possible but it does not grow back at any way near the same rate. I'm ordering more. and hopefully over time eradicate the weed.

It does appear to work! It disperses the algae into the pond pump filter material, which can then be thoroughly washed every few days.

This has worked in the past, but this year no effect, so I don't know whether it's the formula, or maybe the blanketweed has changed slightly
