Hey Boat if your talking about the floating nasty snot looking FA on the top of your water Grass Carp wont mess with that... they will however eat chara which is another from of FA but looks and feels more like a plant. I have used cutrine plus granular and like it. It's a bit pricey but does the job I think. If you can have them some folks use Tilapia to control FA, but you have to make sure you can have them in your area.... Grass Carp will not control floating FA.... Sorry

The only difference between a rut and a Grave is the depth. So get up get out of that rut and get moving!! Time to work!!
