I thought green bubble algae (valonia) came in several shapes, including sausage shapes. I'm told Emerald crabs eat them, although I can't get them in New Zealand so I don't know. Desjardini Tangs are also supposed to eat valonia. I increased my Magnesium gradually to about 1350, kept my kH up at 9 or 10, and put an algaecide in the water regularly. I also dropped the heylide lighting back to 7 hrs a day. It was gone in 2 months as pink coraline algae grew over and choked it.
I can't tell what the red stuff is but I suspect it's not an algae but a bacteria. There is stuff you can buy that kills it, if you find out, let me know, I have a bit of that too! Good luck.
