I just bought a new 90 gallon tank and was wondering what the best type of filter would be.
 
u can go with 2 aquaclear 500 my friend uses them on his tank and its crystal clear all the time
 
I'm not sure! I have heard about under gravel filters but not sure how good they are, I have read both good and bad about them.

You really need to think long term. If for instance you are going to go with live plants eventually you want to go with canisters. The power filters are not as good for CO2 injection. I personally wouold recomend canisters. Besure to get quick release for the can. It takes me about 3 minutes to swap out media in my canister with minimal mess. If you have time I would go to Big Als http://www.bigalsonline.com/catalog/product.xml?product_id=22137;category_id=1721 he has very good prices on filters and look at all of them and also the media that is offered for them. Hope this helps.
 
I like to double up on larger tanks.

Two Eheim 2215's would be excellent.
I also like to double up on aquaclears.

On my 77 gallon I have an Eheim 2028 and an aquaclear 500.
My 50 has two ac 300's and so on.
 
would the Eheim 2217 not do the same thing? It is rated fo 160 gallon tank. I'm kinda new at this, so what is the benifit of doubling up on the filters?
 
Don't look at the ratings the companys give you. Most are underrated. Instead look at things like stocking levels, planted unplanted ect...

Most people overstock their tanks so extra filtration is a good idea. Aim for up to 10 times water change or 900gph. 6 times per hour would be a minimum I would go with. But for messy fish liek oscars, goldfish etc... definatley aim high.

And spliting it between two is a better idea. That way you have better coverage over the whole tank and lessen the chances of deadspots with no current. Also if one breaks down things won't go south so fast.

It would be best to buy 2 of the same filter so you don't have to worry about all sorts of different filter media.

A big tank can be expensive to run.
