Here I'm siliconing the acrylic parts into the sump. I used some books and rolls of tape I had laying around to support the pieces while they dried.
This is how I attached the UV sterilizer to the tank. I used two PVC pipe hooks, and attached them to the back of the stand. The UV fits perfectly.
Here's a zoomed-out view.
Then I attached the hoses. I couldn't quite finish this part because I still need a check valve, which is coming in the mail.
This is where the drain hose meets the sump. I used PVC glue to attach the PVC to the bulkhead, and then clamped the hose onto the PVC elbow.
And here's a view from the front with the doors open.
I can just imagine the fish asking me...
