So far so good! The fuzz has not seemed to come back on the rocks, but I am noticing a little bit still lingering on one of my pumps. My plan is to take that pump out this weekend and give it a good scrubbing and cleaning.
Also I adjusted my light schedule to more on the blue spectrum, a longer ramp up and down time, and only 2 hours of peak light output (12 hours total of light). Not sure if this has anything to do with it, but just something else I messed with to keep the fuzz at bay.
Only bad thing that happened since the black out is my wrasse jumped...

. Must've got scared by how clean the tank was.
@Marc.The.Shark have you tried the black out yet?
