eheim wet/dry canister

[fishdaddy3]

I bought a 108 gallon tank about 8 years ago and it has been sitting around so I finally decided to get it going. when I bought it the guy I got it from was running it as a reef tank and his main filtration was one of those eheim wet/dry canisters, I still have the eheim. I was wondering what you guys thought of using this canister filter with no media and just using it as circulation. The tank is undrilled.
