Had my 46 bow up for about six months now, have developed a great deal of this growing in the tank, I have no idea what it is.

Looks like the beginning of red slime algae what's the temperature at and how long do you leave you lights on for its could also be caused by excess nutrients in the water
 
I appreciate you taking time to try to help djtripoalo, I dont believe this is any form of slime algae. I have dealt with those outbreaks in the past and this does not resemble anything like a cyano outbreak. This algae is leafy and only grows on rock.

The lights are on for 12-14hrs daily which under most circumstances is WAY LONG...but its 2 t-5 10000k and actinic....and one 50/50 power compact that have to pass through a glass canopy that old and coated with hard water deposits (very opaque) temp is 77-78. Among a few softies I also have a Hellfire anemone, rock anemone, and the beast of nutrient devourers a big sea squirt, so I feel that excess nutrient is not a big problem. Run a phosphate reducer pad in the wet/dry. Good amount of flow throughout tank. Every few weeks I toss in a chemipure bag into the box for a few days.

Any thoughts on IDing this algae is appreciated.
 
Your welcome just trying to help out a fellow reefer and I just realized you were talking about that whole thing I thought you were talking about the red stuff on that leafy stuff that's some pretty weird algae you got there bud lol
 
Are the leaves stiff or are they soft? That will help narrow it down. It looks cool though.
 
Its a form of brown algae. There are several different shapes and sizes but I had this in my tank before. I thought it made the tank look more realistic but feared it would take over. I removed it and concentrated on getting phosphates to near zero.
