I've never had an FA problem and I controlled it in two different ways.

The first way was with a combo of 20 KOI carp & 6 Israeli Carp for one acre. With bass as predators I never had any more carp then the ones I put in. A slight down side was some turbidity.

The second way is with just a lot of plants and tadpoles that are great FA eaters. The only fish I have are minnows and will add some bluegill. The upside is very clear water. The downside is too many plants for most people.
