snrub, same here with the water clearing up. After five years of fertile green water and now between the BPW and the cold snap the water has really cleared to where I can see it growing on the ponds bottom in 6 foot of water. My designed spawning area is covered all the way to the surface. Way to much BPW for me. I priced the granular Aquathol and it's around 500 bucks to clear a half acre. I sure hope the GP choose to eat the BPW and not so much the APW. It will probably be the other way around and the APW coverage is almost perfect as far as I am concerned.
