A.T.O.—Automatic Top Off System Water Level controller

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 you reservoir, in the event that your reservoir is low on water. This safety feature prevents pumps from running dry and failing.

Excellent!

Flawless operation by Gman

Comments: Latest version comes with switch to turn on/off audio alert. Works great. Keeps constant water level within 1/8" to 1/4". Pricey but worth it!
Yes, I would recommend this product to my friends.

Excellent!

requires modifications by Bill Smith

Comments: I love the ATO but it requires "marine" velcro sold at TAP Plastics to hold the sensors. Toss the suction cups and plastic rods as they are junk. An internal switch controls the buzzer now.
Yes, I would recommend this product to my friends.
