Best automatic top off system today?

This may be a old question but all the posts that I seen is rather dated. What is everyone opinion on the best ato as of October 2016? My old fashion float valve needs to be retired , I believe! Thank you everyone for looking.

My Tunze has been working well for two+ years now. Not sure if there is better.

Had my Tunze unit working for over 10yrs. The power connector finally rusted out on the brains and required some soldering. I got it wet a bunch of times. I dont think there is a better solution until Apex optical system gets a few more years in the market. The system is really solid and requires almost no maintenance.

Is there any ato that works similarly to a float switch? I have my water supply feeding my sump via gravity. I just need a switch that opens the valve when it is low and closed when full.

Hydro smart level.
No moving parts, alarms and shutdown for too much or too lil water.

yeah I mean just use a standard float valve. Mine is Kent, cost me like $7

Yeah, but hydor smart level and others have no moving parts that can get stuck in the off, or worse on position. Calcium build up, salt creep or snails and you'v got a flood. At least use a double float switch system if you want a float switch system

Could get an electric solenoid valve if it's gravity fed, that is controlled via the electric outlet on the hydor smart level, or another sensor type ato. Just make sure the valve 120v and is plastic construction so it's aquarium safe.
The good thing about hydor, can't speak of all brands, is if for any reason after 10 minutes the max level is not reached it shuts down and sets an alarm. Same thing with too much water, it will hit a higher sensor and turn off/set alarm so you don't come home to a flood.
