Is there such a thing as to much of an algae bloom? Not that I think I have to much, it just seams to be often. And if so what can you do about it?

Also, does one have to kill algae,and remove pond weeds before you put pond dye in?

I caught a nice 3-4 lb CC and it had more of a muddy flavor then ever before. I was thinking it was because the water level is so low and the algae is blooming alot.
