I just got a new 90 gallon Setup! what fillter should I get?

[drizcol]

I just got a new 90 gallon tank and Black R&J enterprises stand with twintube floresent light, glass top, under gravel filerter with 2 660 powerheads, 40lbs of florida crushed coral, and an exter 48" actenic blue bulb for $530. everything was new. Im so excited!
I have had a 29gal set up for like 6 years and I have had it saltwater for 3.5 years. I am using my hang on the side wisper filter from the 29gal in the new 90gal so that it used the baacteria thats been growing in there. I want to set up the 29 gal again and us this same filter and get a new one for the 90 gal.
What is a good one to get? I dont want to spend over $80. I also want it to be super quite and a fantastic filter too. the 2 660 powerheads push 175 GPH each so I know the water has plenty of movment. What are some good choices?
Also Should I get a protein skimmer? what are the pros and cons if any cons.If I should get one, when should I get it??

If I were you I would use at least a wet dry filter on your 90 gallon. A pump filter hanging on the back of your 90 gallon is way to small. You won't get the water flow and the quality of a wet dry with it. Good idea to pawn your old bacteria.
Protein Skimmer filters organics, it pulls out amino acid, and proteins. It functions similar to charcoal.

I have a 90 and run Emperor 400 and 280 along with a Aqua C Remora Pro skimmer. That along with 4 powerheads, 4 inches of live sand, and 80 lbs of live rock seem to be doing the trick. I stayed away from the sump/wet-dry for now being that I'm in an apartment and want to minimize my risk.
Hopefully that helps.

What are you planning on keeping in your tank? You may not even need a filter other than a protien skimmer if you have enough live rock.

The best deal out there I think is the magnum 350 pro system with biowheels ( 90 dollars online ). I have it on my tank with a skimmer and It is awesome and then some.

Is this tank already set-up with the equipment you mentioned? If not, get rid of the undergravel filter and add a DSB. That with ample LR, you should only need some mechanical filtration and lots of circulation. A skimmer is always a good addtion.
