HYDROS ATO Kit: A Smarter Way to Handle Aquarium Water Levels

The HYDROS ATO Kit simplifies water maintenance by automating top-offs and integrating effortlessly with your existing HYDROS system.

What Comes in the HYDROS ATO Kit?

This isn’t one of those kits where half the parts are sold separately. Everything you need is in the box:

• HYDROS Water Level Sensor – Plugs directly into any HYDROS Sense Port

• HYDROS DC Micro Pump – Connects to a Drive Port for smooth, compact power

• Hang-On Tubing Mount – Keeps your tubing where it should be (and not in a tangled mess)

• Tubing – Measures 8.5mm OD and 6.5mm ID

• Siphon Break – Prevents backflow and adds an extra layer of safety

HYDROS ATO Sensor: Accurate, Maintenance-Free Monitoring

Forget float switches and clunky old sensors. The HYDROS ATO Sensor uses solid-state tech to monitor water levels reliably—without any moving parts.
