Refill System 2.0 is an osmolator with 3 float sensors for efficient and safe filling of evaporated aquarium water.
Thanks to the Smart ASOV , no more flooding due to overflow of the reverse osmosis water tank. Smart ASOV stops the osmosis unit in time thanks to a sensor and will avoid any unpleasant surprises!
Auto Aqua 's Smart ATO Duo is a unique automatic osmolation system with two non-contact digital sensors that monitor and automate the refilling of evaporated water.
The Auto Aqua - Smart ATO RO G2 is a solution designed to automate the filling of a reverse osmosis (RO) or RO/DI water reservoir without stress or constant monitoring. Compact, clever, and truly practical for everyday use, it prevents forgetting to shut off the RO system, resulting in smoother operation and a significantly reduced risk of flooding. Thanks to its dual optical sensors , solenoid valve , float valve kit , and integrated safety features, it effectively protects against overfilling. It also helps limit TDS creep by promoting longer cycles, contributing to cleaner aquarium water while preserving the resin. A truly convenient solution for keeping RO water always available.
Red Sea 's ReefATO+ 3 in 1 is not only a connected osmolator, it is also equipped with a temperature sensor and a leak detector.

good product (Translated review)
Cédric A.
It hasn't been in use in my tank for very long, but so far it's working well, even though the osmolator spins in a vacuum when it's switched on, without levelling the water. (Translated review)
