I know sorry about the picture quality. I did a winter drawdown and lowered by maybe 2 feet hoping to kill off some of this vegetation over winter. That was one of many that got sucked through the 2" pvc pipe. I took a last minute pic. I sucked up quite a bit of this and it didn't appear to be rooted.
What would be a good to use to kill this off? I added some GC last summer but am doubtful about the survival rates, pond is out of balance and I have mainly very large bass. Have not seen any signs of them either. So looking for a better option for the time being. Would I be better off dying or fertilizing the pond at this point?
