KAI Saltwater Kit
Effortlessly cultivate your cove with the KAI Saltwater Kit by Felix Smart.
What's In The Box?
This saltwater aquarium-focused KAI kit comes equipped with KAI—the Felix Smart controller—and a suite of sensors, including probes that measure Acidity (pH), Electrical Conductivity (EC), Oxidation Reduction Potential (ORP), Total Dissolved Solids (TDS), Salinity (SG), Water Temperature, and Water Presence. These probes provide real-time data on the critical parameters that affect the well-being of your fish and coral, allowing you to take action before any issues arise. KAI also uses these environmental parameters to automate your devices.
Stay Connected To What Matters Most

The included 1080p HD camera offers an even closer look at your tank, letting you keep an eye on your aquatic life from anywhere, at any time. The camera can be easily integrated with the KAI app, which enables you to time-lapse the growth of your ecosystem.
