Magnetic RODI/ATO Safety Float

(3 customer reviews)

SKU: ATO-FLOAT Category:


The new Coral Box N30 ATO fits standard 1/4″ RODI tubing, and includes an adapter to fit the tubing included with all of our Auto Top Off systems.

These include a sturdy magnet mount that works with glass up to 3/8″ thick. The unit is designed to be placed a few inches above your desired water level. If your ATO were to siphon, have the pump run too long, etc. this float switch will physically cut off the flow of water, preventing an overflow.

No ATO has a 0% failure rate, so these are an excellent addition to any ATO system to add redundancy and safety to your aquarium!

These are also super useful for RODI systems, you can mount this in any bucket or aquarium, no drill hole required.

    Great product does what it says….I just wish the magnet was a little stronger…the float when it pushes up tilts the entire valve
