Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Is it too early to attack the pond?

thanks, Scott. My plan is to plant some hardy lilies like Bill has, but the location is right were the worst Chara is. I can't rake once the lilies are in place, even though the lilies will help with controlling the chara. I will rake, but when should I start treating? is there a better solution than GreenClean Pro? Would the liquid be better than granule for this problem?
