HYDROS handles control. Reef Trak handles records.

HYDROS controls equipment in real time and stores recent probe data. Reef Trak tracks the long-term reef-keeping history. Parameters from any source, dosing, livestock, equipment, maintenance, expenses, and TrakAI exports.

How HYDROS and Reef Trak work together

Reef Trak imports HYDROS probe readings (pH, temperature, salinity, ORP) through the HYDROS API on a regular cadence. They appear in Reef Trak's parameter history automatically, alongside manual test results.

Then you get everything in one connected record. HYDROS probe data plus kit-based testing plus dosing logs plus livestock additions plus equipment maintenance. TrakAI exports the combined history for AI analysis.
