Thanks again. I should have mentioned that my new tank was drilled for a Beananimal set up but through the bottom, so my overflow AND plumbing will both be internal. With this in mind wouldn't I be able to just drill into the top of the 90 of the open line without the use of the airline and fitting? Would this not work the same way with the hole serving the same purpose as the open end of the tube. If a blockage occurs in the first Siphon line then wouldn't the water rise, cover the hole and then turn the open line into a full siphon much the same way? I would assume the only reason a tube line is used is because of the plumbing being external.
