Wow Will,you did a complete makeover on that tank.That internal tower overflow right in the middle of the tank had to be an eyesore.The new display looks so much better without it.I think you'll find that your sump/fuge will be much more effective than the wet-dry you had previously.Great job,i'm looking forward to seeing it progress.
BTW,remember that with a small return pump section,the water level will drop alot throughout the day.It will eventually be a PITA having to constantly refill that section.Since your sump/fuge is acrylic you can drill it yourself to fit a float-valve in it.This is a cheap but reliable way to provide auto-top off via a gravity fed reservoir or RO/DI water that is plumbed into the valve.If you have any questions on setting it up,drop me a PM or do a search here on CR.There's alot of threads about auto-top off that should provide you with the info you need.
