First,,grass carp will not control FA. tilapia will die in cold weather. When you reach for the chemicals what happens? With no plants left to help soak up the nutrients FA takes over. In my experience 20 KOI and 6 Israeli carp per acre controlled the FA. With Largemouth Bass to control the carp offsprings. I also had grass carp for some plant control. Then I had the usual other kinds of fish including Channel Catfish with also will eat FA. I use just a little bit of chemicals to slightly control my cattails in selected area. So what happens when I do kill them. The following year these areas have FA. It's that simple. Chemicals lead to FA, then it takes chemicals to control weeds
and FA and you're in a vicious circle as I see it.
I took out Eurasian Millfoil in a completely choked pond in four years using 18 grass carp per acre. This would be a disaster to bring on FA but the other combination mentioned above took care of the FA.
One other thing...plant create oxygen...
