Tired of lifting heavy buckets to refill sumps or tanks due to evaporation?

There is finally 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 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 LED panel + our innovative Audible Signal alerts when in operation mode.

Linkable Brackets
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.

Specifications:
* Power Supply for Pump Capacity: 2A
* Dimensions (L x W x H): 1.5" x 2.75" x 4"
* Weight: 2lbs
* Pump: (Not Included)

4 out of 5 stars Works great after tweaking
by from Maryland on 10/19/2009
Recommends it to Friends: Yes
The JBJ ATO worked great after some tweaking. I have a 20 gallon tank and I am using the AquaLifter along with the ATO. The issue I original had was with the 3min 45sec factory float fail-safe safety feature. Everytime the float sensor would trigger the aqualifter, it was taking longer than 3min and 45sec to fill. As a result, the ATO would stop working and I would have to do a manual reset. I did not realize that there was a way to adjust the float fail-safe duration time since it was not part of the manual. If it wasn't for Google, I would have returned the product. For instructions on how to adjust the float fail-safe time duration visit the link below. It will save a lot of frustration.

5 out of 5 stars Great Product
by Tom from New York on 5/26/2009
Recommends it to Friends: Yes
Although the directions could be better, the electronics in this product keep the water level on a line I have drawn on my sump! Replacement RO water is drawn from a ten gallon tank reservoir equipped with a AZOO pump that is plugged in the ATO. Sensor A is in the sump and sensor B is in the reservoir. The ATO has a mode switch so you can change locations of the sensors. It is important when you mount the sensors to do so with the wire facing up or else the sensor indicator red lights on the ATO will remain lit. Once set up properly, the green power light remains lit and the only light to come on is an orange pump light. There is no sound when the pump light is lit. Pump is on barely a second at intervals throughout the day and night and my sump water level remains constant. Protein skimmer works better now and salinity is stabilized. All I have to do is fill the reservoir tank about once a week.
