Ran into a guy that has used this product in his potty pond to control what looked like coon tail and he said he had duck weed, He had to apply every 7 days. It did a number on his pond, I seen the pond before the treatment from afar and it a months time he has almost cleared it up. The guy that recommended it to him said it will kill anything green including DW, has anyone ever used this before? I have a buddy that has a potty pond that he would like to clear up, but I dont want to waste his money on this if it wont work on DW.


A little snow, Please!
