Wee-man, any idea why it is just on one rock in one spot ?It sounds (rather than looks) like asparagopsis sp. possibly taxiformis - red hair algae, it should die off as your tank parameters improve and kept spot on.

PO4 has been behaving, 2 feeds a day, one flakes, one nori, fish have been on diet for the sake of the Bird's nest project.
All food eaten within 10-15 seconds
A better pic required, slime makes it sound like cyanobacteria
Looks a bit more like cyano, it is part of new tank syndrome, run a phosphate remover and keep your parameters good, it will soon get better.
Cyano and diatoms feed off P04 and nitrates, so the quicker you get the water params right, the quicker it will go away, but be prepared for it to get worse, but just remember we have all been though it, it's a right PITA but it happens.
