I don't know if I can top that response, Chad! Well done.
The only thing I can add is that I don't think you're likely to have a fish kill from decomposition of winter filamentous algae blooms. I'm unaware of any instances of that happening. Usually the water is still quite cold when the filamentous algae starts to go away, so you've got water that holds a lot more dissolved oxygen at the time, and the fish's metabolic needs aren't as high. For me, in the past, it's been mostly a nuisance.
