Recommendations for skimmer on 80gal

[kam]

I have an 80gal im in the process of setting up. Doing it slowly..ish.

Its a none overflow setup. Using a canister filter, mp40es and koralias for water filtration and flow. I need a skimmer for it as I dont want to use my big bulky CSS.

Will a Prizm Deluxe do? They say "up to 100gals" but Im not sure if I believe that for the size of it...

What do you guys recommend? I am on a budget

Thanks
