Your reactor needs to be the lowest point in the system if you're not going to run a secondary reservoir. I would recommend doing a search for that as well, they really keep things cooler in my experience.
Do a search for the other bubbler designs out there and a secondary reservoir, other than that from the pictures you posted I can't see much else. How long is your current bubbler?
