Neptune Systems ATK Automatic Top Off

SAFETY MADE SIMPLE
The ATK (Automatic Top-off Kit) is a simple, standalone, and complete solution for replacing water lost to evaporation.
The new aquarium hobbyist has many challenges, but none is more annoying than the chore of adding water, every day, to make up for that lost to evaporation (a.k.a. topping off/up). This alone usually makes the automatic top-off (ATO) device the first piece of automation equipment purchased.
The ironic flip side of this decision is that a faulty ATO device is one of the leading reasons for catastrophic aquarium failure, or even worse, flooding of the house or business.
Not all ATO devices are created equal. Sadly, many ATO on the market are made with cheap components, have very little protection against these catastrophes, and are just a nightmare to assemble and install correctly.
An ATO does not have to be both a blessing and a curse!
We designed our ATK Automatic Top-Off Kit to not only be super-simple to install and use, but it is unique in the market asanATO device with three layers of redundant monitoring and water-level control. The ATKdoes the work for you, while at the same time protecting your tank and your home.
