I'm in the process of setting up a 360 gallon tank. 
I have a diy 75 gallon wet/dry available. My LFS is carrying the Ultima line and I'm wondering if these filters are that much better than a wet/dry. My LFS is ranting about how well they're working for him on his ray tanks and koi ponds.
Here's the filters. They're not cheap either.

Thoughts? Any good? Better than a wet/dry with capacity for about 25 gallons of bioballs?
