Tired of lifting heavy buckets to refill sumps or tanks as a result of evaporation?

There is in any case a professional grade product that automates refilling evaporated water. The All-New A.T.O (Automatic Top Off) device is the most advanced water level controller system in the marketplace. Lifting heavy buckets and spilling water is now a thing of the past. Maintaining stable salinity and specific gravity are no longer a problem since the A.T.O. will refill as soon as the water level drops. The A.T.O. will keep all salt levels at consistent parameters, ensuring an optimal environment for your tank inhabitants


The A.T.O. is equipped with (2) waft sensors that activate within seconds when your water level drops and automatically refills your sump or tank until it reaches your desired set point. Each waft sensor has been designed with an exterior guard preventing snails & hermit crabs from attaching to the sensors.

Our cutting-edge electronic controller allows for (2) modes of operation with a total of (3) different set up scenarios, allowing you more choices for installation for your unique set up. Our compact controller also incorporates a visible L.E.D. panel + our innovative Audible Signal alerts when in operation mode.

Your professional kit includes commercial grade “Linkable Brackets” that can easily be adjusted to meet your height requirements, and securely positions your waft sensors. Many competing brands use inferior suction cups that are temporary that can lead to disastrous water spillage.

The A.T.O. automatically stops power to your return pump in your reservoir, in the event that your reservoir is low on water. This safety feature prevents pumps from running dry and failing. (Mode A- Example 1)

At SaltwaterAquarium we strive to do things different. We aim to keep things simple and only sell products we currently own or have used previously. We are saltwater enthusiasts just like you, why would we sell you a product we would never buy ourselves? That’s just silly. There’s thousands of online stores, some who are cheaper, who simply try to sell anything and everything under the sun, they may be able to without reference to quality. Here at our eBay store we only sell items we know work and have great value. This does a couple of things for us.

  • We know the products inside and out, because we use them in our reefs/tanks. We will have to be capable of answer any question you have.
  • We hardly ever have complaints or returns because we do not sell the low end products with bad reviews that do not work.
  • Setting up our store in this manner makes for a better overall experience for you the customer.
