whats your opinion on running a GFO? necessary? not necessary?
My 60G Cube has a deep sand bed, about 4-5 inches with about 25 lbs of reef rock.
Its still cycling at the moment. I'm just curious to know opinions. ive had slight issues with phosphates in the past, will a GFO make a significant difference?
