What is turf?
In an old tank, I had this maroon colored fuzz, almost like small cotton balls that really started to overgrow everything. That's what your first picture looks like to me. I had to harvest it manually and I never got rid of it. Nothing would touch it; tangs, crabs, or snails. I had to break down the tank, buy new live rock and start over. Let's hope this isn't your situation.
