Start Measuring Salinity in Your Reef

Replace an old probe or add salinity monitoring to your Apex Aquarium Controller. Maintaining consistent salinity in your aquarium is key to the well-being of every organism inside it. Often, we're so busy that we overlook changes in the salinity of our reef aquarium until problems arise. With real-time salinity monitoring, you can be alerted to potential issues and do something about it.

No Salinity Port? No Problem!

If your Apex doesn't have a salinity probe port, you can easily add one with the separately available PM2 Salinity Module. The PM2 Features a salinity probe port, temperature probe port, and an I/O port.
