Why Choose Ultimate ATO ?

With TWO dual-optical sensors, the Ultimate ATO is the first ATO to include 4 sensors. The 4 sensors allow us to design a dual-stage overfill alarm that is less intrusive as well as a run-dry protection feature that prevents your sump from running dry: which is also a first.

The Ultimate ATO’s versatility is also unmatched. An efficient DC pump is included for a standard installation. If you require a larger ATO pump for a remote sump installation, a Socket Switch is included that allows you to run a pump up to 10A (1000W). A solenoid valve is also included for aquariums that are topped off directly with an RO/DI system.

We designed the Ultimate ATO to offer you the ultimate protection with the ultimate convenience!
