Yeah, if you wanted to get real fancy, a slip union would help. But like I said, the inside tank plumbing isn't glued, so some room for adjustment up and down anyway. I still have a good portion of a 20' PVC pipe left over, so no big deal cutting new pieces. 
 
I see you like DIY stuff, too. Good job... 
 
I am setting up another 140g tank downstairs, and trying to figure out all plumbing in my sump room. My current 100g DT is upstairs. I will share the same sump initially, but then will set up another sump into this already tight room. Never ends...
