Thanks for all your replies!
I don't have a problem with vegetation at this point, when I renovated my lake I had the edge dug to about 2 feet all around the shallow end, So I have not used any dye at this point. In my situation it is cheaper to feed than to fertilize and a heck of a lot easier. I have 3 Stren feeders that feed 12 lbs. per day each for now. Any advice would be appreciated!
