Could use more info.
How old is the tank?
What are your levels ( need #'s to help)
How big is the tank?
What kind of fish?
How long have you had it?
Where do you get your water? (ro? di? tap water?)
What filters?
What/how many lights? And how old?
The red stuff on the rocks is probably red slime algea. Congrats... you officially have gone to war with the same beast we all have. You'll win. Just need the right tools.
Algea (red or otherwise) is feeding on something. Something in your water or from the lights.
But to make a better assesment I'd need your specs. I fought for 6 months algea problems. Almost gave it all up, and then the last piece fell into place and it's all good. (knock on wood)
