I've tinkered with some of these tiny pumps. It would probably work but won't give you much room for expansion.
It may or may not give you enough flow to use a timer and you will be working with small tubing if you try to go with auto siphons so you may find getting everything flowing just right to be a bit fiddly.
Here is another option, it is the pump I have running my aquarium system, my quarantine wing, and even one running my solar heater even though I suspect the hot water isn't good for it. I have even tested one out to run the barrel ponics system and it is capable of pumping enough water up about 6' for that system.

And it is fish safe. Hooks up to 1/2" threaded fittings easy enough.
