A good quality solenoid on a good quality timer. I use a 12v dual float switch on a relay. That fills from my reservoir. Good luck

SpectraPure® Multiple Tank Liquid Replenishers are the most advanced means of controlling liquid levels on single or multiple reservoirs and are ideal for replenishing evaporated water in aquariums or liquids in other constant level containers. A sensitive air pressure switch opens a solenoid valve when the liquid level drops approximately 1" and closes it when the liquid level rises back to its original level.
Research at SpectraPure® shows that the Multiple Tank Liquid Replenisher provides a significant advantage over conventional float and back-pressure activated automatic shut-off valves by maximizing the duration of membrane operation. This minimizes the build up of impurities due to membrane creep (the small amount of impure water that is a characteristic of the membrane at the onset of pure water production).
All wetted components are constructed of inert and saltwater safe materials. Power is provided by a plug-in 24 volt AC (UL listed and CSA approved) transformer.

It's always a good idea to have at least 2 switches to turn off your auto-top off and even better if those 2 switches are different types. I have a double float valve switch and I also have an optical switch as a last resort. This way I don't have to worry about the age of my float valves. When the first one fails, hopefully the second one is still good. If not, it will hit the optical and I'll know to replace my float valves. I also have an Aquatronica controller, so I will see a decrease in my salinity and will probably be notified by email when it happens, as I'm guessing my salinity will drop enough to trigger an alert.
It's also a good idea to have a sensor in the tank near the overflow to stop your sump pump from overflowing your tank. I will use an optical sensor for that but I haven't hooked mine up yet.
