The thing that is mostly hard to keep stable in small systems is the salinity level. Water evaporates, salt doesn't. This means that the salt content ratio in the water will rise like crazy, very fast in a small system. With an auto top off, it replenishes the system with fresh water the second the water level drops even a bit. This will help you get a stable system.

Hope this helps man. If you have any other questions just shoot me a pm. I've been doing this for a couple years and have gone through a couple tanks.
