Sump return plumping?

[Shanasman450]

I'm having some trouble figuring out how I could do a soft return line from a sump. I'm planning on switching from a canister to a 10g sump for a cleaner look and easier maintenance. The problem is, the tank is already up and running and I don't have a viable way to move our livestock anywhere to drain it, so I have to go the hob route. Most threads and videos I've seen mostly talk about the equipment itself and leaving out plumbing, or talk about plumbing from the standpoint of having a drilled tank, so I'm having trouble finding info on hang on/over return setups.

My question is, assuming you had a tank running and drilling isn't feasible, and assuming you wanted a clean look but also wanted to keep costs down, how would you go about setting up a return line?

I didn't think there would be, but I've been bitten by not asking questions that I should've cause I thought I knew the answer already. I appreciate the input

I’m happy to respond, I trust if I get it wrong others will respond and give us better understanding of a subject.
