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.
If you already have an Apex of ANY kind, setting up the ATK is still super-simple. Just plug in all the components, attach it to your Apex via the AquaBus cable, and then run the set up task inside Apex Fusion. With the ATK connected to an Apex, you get the added benefit of having email/text/iOS alerts if there is an emergency and you can integrate its operation into other functions.
IQ-Fill (standalone mode only)
IQ-Fill is an intelligent and learning algorithm that, ongoing, monitors and records how much water your aquarium needs for each fill, and then calculates a maximum time your pump should run. By doing this, it dramatically reduces the chance that your pump would continue to add large volumes of water to the tank before you could realize it and fix the situation
Back-up mechanical float valve
While a float valve mechanism itself is certainly no high-tech solution, it is exactly what you want to have in place should all this high-tech gear decide to fail. The float valve on the ATK will never see any action unless for some reason the electronics continued to add water to the tank despite the optical sensors being submerged and the IQ-Fill algorithm limiting run times. For those small systems (usually small all-in-one aquariums) where the float valve will not fit, you can remove the float valve from the bracket and you still will have two levels of safety backup.
PMUP – the most powerful pump
provided with any ATO!
The PMUP is a 24V utility pump that is perfect for moving water from your RODI reservoir to the aquarium. This pump has a vertical design that easily drops into most water jugs or ATO reservoirs. The best part about the PMUP is that it has the the power to deliver water to your tank even from remotely located water reservoirs. Most other pumps that come with an ATO will barely pump six feet, the PMUP though has the ability to pump over 14’ vertically so it can even pump water up from a lower-floor or basement water storage location!
