Help identifying strange algae

[Baldy]

man, at times all this makes me want to pull my hair out! (made more funny by the fact im bald =P). I am reading up on chemiclean. and it seems for some reason like every time i research nutrient reduction methods, or algae control, i come back to carabon dosing. I want to try vodka dosing, but biopellets are a carbon source as well. If results from vodka are anything like they were from biopellets, im not going anywhere near them!

maybe this is a topic for a new thread.
