Thanks ewest... I'm going to try a pond or two with aquathol, and a couple with aquathol & reward to see what type of efficacy I get up here. It's probably cheaper go with Aquathol if it lasts twice as long.
I have used hydrothol + reward, it has been quite effective against stubborn FA. I think a lot of the ponds in this area are starting to show signs of CU resistance. One pond I treat has CuSO4 bags visible on the bottom, the guy says "oh well, I just got tired of spreading it so I just threw the bags in". WOW.
