The 110 level up.

Looks great! I think it's a bit of a shame the return lines are drilled so low but I guess you'll just have to work with it. Just watch your creep back-flow as lockline doesn't really seal 100% at the joints, might want a check valve. Another alternative is to replace the first fitting on the inside with an PVC elbow and hard pump it up in the tank a little before using your lock-line, that way you'll be able to point your nozzles down making them more useful and should also be less obtrusive.

Would think with those light supports you could run the power wires and such through the tube. Is that not possible?
