Level control / ATO
With a Level Control / ATO system you no longer have to top up the evaporated water every day. Level control / Top-up system for your (sea) aquarium ensures automatic top-up of evaporated water. This is generally done by means of a float or an optical eye which measures the water level. If this is too low, a pump or solenoid valve will be switched on to top up water until the desired level is reached again.
