I use a herbicide also. It's called AquaPro, and kills everything. The problem is that it is not selective to cattails. I like to have some of the cattails to provide cover for YOY fish. Otherwise, the bass and bluegill have a field day with the hatches and recruitment is low.
The weed razer just allows me to be a bit more selective about what is removed. It also allows me to collect the cut floating cattails for removal from the system so that they don't add excess decaying matter to the pond.
What I would really like to get is a lake mower, but holy smokes those things are expensive.
One could just spray a few here and there with the herbicide, but in my case my pond bottom is so fertile it would be a never ending battle.
After they turn yellow from the herbicide I cut them off and remove them so there isn't much organic matter left in the pond.
