+1 I agree with Al... IMO a good surfactant improves the performance of both herbicides and algaecides. Some come with the surfactant already in the product so read the label. There are several good surfactants on the market (I use Cygnet Plus). Make sure you get one that states it is non-ionic and ok for pond use.
