So now I am thinking of adding a GFO to my reef. Which unit do you guys recommend I was looking at a couple on BRS and I found the single unit supports about 120 gallons. He also mentioned to do 50/50 with gfo and carbon and if that's the case, it will support about 60 gallons. I was looking into the dual too and was thinking maybe gfo in one and carbon in the other? what do you guys think?
