If you want a nicer looking hose, you can use clear PVC/Vinyl hybrid hose (same as used on Python no spill systems).
Also your 800gph pump wont be pumping nearly that fast by the time it gets up to your tank. Look at the flow chart for the pump you want to use at the height you want to pump, take that value and reduce it again by probably 25% for the frictional loss from the hose, and that is the realistic flow you can expect at the tank. A ball valve on the end is a great idea to shut off the flow when you are done filling and wont hurt your pump for the short amount of time it takes you to go back down stairs and turn it off.
