I,m looking to buy a skimmer even though my local fish store has told me i dont need one . Seems like from what I read at this site I do and I trust you all alot more than I do them. Anyway I,m looking at a seaclone which they say will handle up to a 100gal tank, its 17'' high and comes with a maxi-jet 1000 pump. Will this be enough for my 20gal tank which 2 clowns 2 damsils and 4 anemonies , 10 small snails and 2 turbo snails and 1 sand sifter star.I also have 20 lbs of live rock.Yeah I know to much in the tank but I,m getting a 29 gal tank soon. anyway any advice welcome thanx, dave e
