Sid,
Not to be mean, but then you will want a bigger tank.
The main problem is the tang, the 55 is just a bit too small for them, most recommend a 75 or 100 I think. If you drop him out of the mix you might be okay.
On my 55, I am running a 15 gallon sump and a 20 gallon fuge. I have about 85 lbs of live rock between the tank and fuge and a DSB and protein skimmer. And then a tank turn of about 15X a day between mag pumps and power heads.
