Completely depends on the capacity of the filter, I would go with a canister or a sump, but for a beginner I would go with a canister rated for at least a 100 gallon (they tend to say they can handle much more than they actually can)
I like canister filters myself, But since you are new to the hobby, i would recommened HOB(hang on back) filter as they are easy to clean/maintaine and cheaper.
aquaclear hob 100g filter would handle it nicely. then maybe the one you already have on the opposite side. thats as far as cost and maintenance. but if you have the money canisters are great
