My tubing is bent coming up to the out/in flow pipes, they are coming from behind the stand. Is there such a thing as a elbow for these 12/16 mm tubing?
Search e bay for "eheim elbow" as they have some there but not sure it's the size you need. You can always bring your hose to Home Depot as well and try to match it up to what they have in stock. Pick up some hose clamps and you should be all set.
