SK,
Keep me posted on your success. It has been hot and dry. It looks like I'm starting my second algae bloom of the year. I also see a little FA in the shallows for the first time this year this week. I didn't put tilapia in yet, but I might still do it just for kicks. The 2 times I used fluridone, I undertreated on purpose, trying to just treat eurasian milfoil and it worked very well for me although it definitely is a slow kill process..
