Thanks all for your help, I moved the aqua lifter above the brute can, changed out to rigid, RO/DI type hose for the siphon break line and moved the T right next to the aqualifter above the brute can. Seems to be good so far. I like the idea of a solenoid and a peristaltic pump, but like I said I want to make it work with what I have, at this point I'd rather put money towards livestock. The PVC, air gap/gutter setup is what i'm trying to avoid as I don't think I would like how would it look. Putting the fill tube into the display would definitely work, but like someone mentioned above, the display is on the other side of the wall. A peristaltic pump is definitely on my future list of upgrades. It would look a lot better too without hosing going all over the place.
