Fuge all the way my 46gl has a 30 gallon fuge, my 29 bio cube has a Esshops rs-75 converted into a fuge in the stand, my 80 gl has a 40 gallon fuge all running Chaeto on a 24 hour light cycle. I could not imagine running any of them without it. I don't run any reactors and always have 0 phos/trates in the system. My sand is oolitic sand topped with miracle mud 5 inches deep.
