I have some kind of black algae in my refugium. I also have some gren hair algae and some reddish looking cyano in there. I am not sure what it is. Everything else in there is fine. I keep the temp between 77-79F. The salinity is 1.024-1.025, Ca is 475, Mg is 1300, Ph is around 7.9-8.1. I can try to take a pic if needed.

generally speaking, algae in the fuge is to be expected. Is your question why is it there or how to get rid of it? 99% of algae issues are problems with nutrient export - too much in, and too little out....

There are several ways to accomplish nutrient export. You can feed less, skim more aggressively, put chaeto / caluerpa in the refugium, or look into running a bio pellet reactor as well.
What kind of light do you have over the sump, how old is it, and how long is it run?

I only feed two or three times a week (Elos SVM2 Granular Marine Fish Food - English), every time I put either cheato or caluerpa in the fuge, the algae overtakes it and kills it, how do I skim more aggressively (more wet ot dry?), I run a phosphate reactor with GFO ( http://www.bulkreefsupply.com/store/1-pound-453-grams-bulk-gfo-granular-ferric-oxide.html) and activated carbon (1.5 Pounds- Half Gallon Premium ROX 0.8 Aquarium Carbon - English), can I use a bio pellet in there also?

Do you have any type of flow in the fuge? And do you shake the chaeto or caulerpa occasionally? Once I up'd the movement in my fuge area and started really stirring the chaeto, I found that the algae couldn't settle on them. Plus make sure you have enough light on your fuge. Around 100w (or equivalent) and 6500k works well for mine.

How old is that light, and how often is it running?
