Skimmer vs Refugium or both?


New member
I currently have a small skimmer that needs to be upgraded. My question is, should I get a larger skimmer or set up a refugium or do both? I have a 120gal reef tank with small bio load, the skimmer is biult into the wet/dry and is only 12"x3" ,venturi type. My goal is to help get rid of some brown algae and benefit the corals. I have the nitrates down to less than 5 ppm and phosphates to .2 ppm and still have problems with the algae. Any suggestions would be helpfull.

I'd likely do both. With that level of phosphate, you might want to consider using a GFO like PhosBan.
