So I am running a Eheim Pro 3 2080 for my bio filter & a 50 gallon sump running 2 separate pumps each feeding to a seperate sock for mechanical filtration. Does this seem like a good amount of filtration for my 180?
You should be good depending on the pumps your using and even then, its a question of turnover rate, but I would add bio to the sump. Something submerged like ceramic rings, pond matrix, etc
