The AquaFX Dual Vertical Mount Float Switch pack provides two essential components for automating and safeguarding your saltwater aquarium. These switches are designed to monitor water levels within a sump or auto top-off (ATO) reservoir, activating or deactivating equipment like pumps or solenoids. By accurately detecting high and low water points, they help prevent dangerous overflows that can damage your home and equipment, or stop pumps from running dry and burning out.

This package includes two vertically-mounted float switches, which can be configured for either high-level or low-level notification. The vertical orientation is ideal for easy installation in most sump baffles or ATO containers. Having two switches offers incredible versatility and security; you can use one to trigger your top-off pump and the second as a high-level emergency shutoff, providing critical redundancy and peace of mind against the potential failure of a single switch.

This dual float switch pack is perfect for the DIY hobbyist building a custom auto top-off system or any aquarist needing to replace worn-out switches in their existing controller. It is an indispensable safety measure for anyone looking to protect their investment and maintain stable salinity with minimal effort. For reef keepers who prioritize system stability and protection against catastrophic failure, this dual pack is an affordable and reliable solution.
