Red Slime Algae

[Reefer Rob]

You'll have no problem with a 3 day blackout. I did 2 days with my SPS tank with no problem. When you re-start your lights start with 1/2 time and slowly work back up. All your cyano will be gone...for now

I wouldn't worry about cyano too much if your tank is only 6 months old. The only thing I know for sure about cyano is that it takes advantage of change in your tank- good or bad. In the first six months your tank is a constant state of change!

My tank is as clean as you can get without run something like Zeovit, I have 60X flow, and I'll still get the occasional patch of cyano, it's no big deal. It usually means a snail has died or something, LOL and the place it grows best is in the high flow areas.
