Pickup currently unavailable
Tired of lifting heavy buckets to refill pumps or tanks due to evaporation?
There is finally a professional grade product that automates refilling evaporated water. The reliable A.T.O (Automatic Top Off) device is the most advanced water level controller system on the market. 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
ADVANCED FEATURES Float Sensors
The A.T.O. is equipped with (2) float 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 float sensor has been designed with an exterior guard preventing snails & hermit crabs from attaching to the sensors.
Electronic Controller Module
Our state-of-the-art 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 float sensors. Many competing brands use inferior suction cups that are temporary that can lead to disastrous water spillage.
Pump Safety Protection
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)
Q: How large of a pump can I plug into the A.T.O.?
A: The A.T.O. receptacle will handle pumps up to 2amp capacity.
Q: Why does my A.T.O. automatically shut off after a few minutes of operation even though the water level has not reached the float sensor?
A: All A.T.O. Controllers have a factory "Float Fail-Safe" duration time period of 3 minutes and 45 seconds of operation before power to the pump is turned off. The Pump LED will glow but power to the pump will not be turned on. This feature was designed to act as a safety mechanism in the unlikely event the float sensor(s) failed or if something was to get stuck in between the sensor(s). You will have to reset the float sensor(s) to restart the controller.
Q: Can I adjust the "Float Fail-Safe" duration time period?
A: Yes, the duration time can be extended to 14 minutes of operation. (Please see instructions included with the product)
