The back of a JBJ Nano is not only plastic , but there is glass with a plastic coating. You can use the existing over flow filter and drill the hole in the back of the tank slightly lower then the top of the over flow inside .Make sure you can get the bulk head into the over flow compartment you can cut 1/2 the threads of the bulkhead if needed. I use an over sized bulkhead and then run the return inside the over flow pipeand attatch to the existing return ! That way its one less hole to drill and less tubes coming out the back of the tank. Nano sumps are nice because you can go longer with out top off and do 50% water exchanges with out leaving the corals High and dry. ( if your sump is equal to the tank in volume.)
