Auto top off pump help

[Klatt]

Hi guys! Brand new to the forum, and to reef tanks. I just completed setup on a 100G tank I switched over from freshwater. I have my RO/DI system in my basement directly under the tank on the main floor. I used my old return pump from the freshwater setup as a fill pump for my saltwater reserve. I plumbed it to fill the sump for water changes, and it seems to work pretty slick even with the large head pressure added. My question is if anyone has any ideas for a auto top off pump that would work, pushing water from basement straight up to main floor, about 9-10 feet. I dont want a big pump just enough to top off. Will most smaller pumps work if I reduce the tube diameter sufficiently right after it leaves the pump. 1/4" tubing maybe.

Thanks in advance for any advice or tips!
