HYDROS Salinity Probe Kit | Continuous Aquarium Salinity Monitoring System

Maintain Stable Salinity—24 Hours a Day

Salinity is one of the most important water parameters in any saltwater or reef aquarium. Even small changes caused by evaporation, top-off issues, or equipment failures can stress fish, corals, and other marine life.

The HYDROS Salinity Probe Kit allows you to continuously monitor your aquarium's salinity through your HYDROS Controller, giving you real-time readings, historical data, alerts, and automation capabilities.

Whether you're maintaining a mixed reef, SPS system, fish-only aquarium, or coral propagation setup, the HYDROS Salinity Kit helps you catch problems before they become disasters.

Please Note: A compatible HYDROS Controller with a conductivity probe port is required and is sold separately.

Why Monitor Salinity?

Unlike a handheld refractometer that only checks salinity when you remember to test it, the HYDROS Salinity Kit monitors your aquarium around the clock.

Benefits include:

• Continuous salinity monitoring

• Instant notifications if salinity drifts outside your desired range

• Historical trend graphs inside the HYDROS app

• Early detection of ATO failures or excessive evaporation

• Improved stability for sensitive corals and marine fish

• Integration with the HYDROS automation ecosystem

Knowing your salinity every minute—not just during water changes—helps create a healthier, more stable aquarium.
