This is a good solution in many cases, the main thing is A (the end of the hose) must be above B (the reservoir water level) and to avoid a back siphon, the hose cannot touch the surface of the water.Awesome notes. I feel like siphon 3 seems to me my most likely culprit. I will play with my positioning a little and see if I can't remedy that siphon issue. Wondering if my best bet wouldn't be to just run my top off hose straight to the display. I sure do appreciate your help!
