whoa,slow down their a bit upgrade very fast all of those fish are going to outgrow your tank quickly in about 3-5 months but name the species of fish like what kind of triggers,eels groupers, and prepared to get flamed

In the other post, you said you were looking at larger tanks so I am not even going to comment on that aspect. You know yourself that your tank is overstocked.
A sump would be much better for you. If you do not have a lot of live rock (80-100 lbs.) I would say you need a wet/dry filter with that stock load.
