What flow rate for skimmer?

[crosby87]

I'm setting up a sump/fuge for my 90 gallon tank in a 20 gallon aquarium. My LFS said I would be getting 400-500 gph to my sump. I want to put a protein skimmer in my sump, but don't know what size to get.
There is one skimmer rated for up to a 160 gallon tank, and another skimmer for a 75 gallon tank. Would I be able to use the 160 gallon skimmer in my sump?
Thanks.

Depends on the brand & type but usually you can. Whenever you can always use a bigger skimmer. Manufacturers tend to overstate what they can do.

I'll go with the 160 then. Since I'm on a budget, I'm going to try to get away with the Odyssea 160, I look at some reviews from some other posts and they say the skimmer works great for the price. On top of that I'm going to add my Aqua C Remora hang on back skimmer just as an additional skimmer since I won't be using it once I take my 55 down
