TankLog: Reef Tank Tracker

Your reef deserves better than a notebook. Log parameters in seconds, spot trends before they become problems, and never miss a water change. Dive into TankLog today.

TankLog is the logbook your reef tank has been waiting for. Track water parameters, identify your livestock with on-device AI, calculate safe dosing, and stay on top of maintenance — all in a beautiful, ocean-dark interface.

LOG PARAMETERS IN SECONDS • Quick-log sheet for salinity, temperature, pH, alkalinity, calcium, magnesium, nitrate, phosphate, ammonia, and nitrite • Interactive charts with ideal-range bands over 7 days to 1 year • Color-coded status at a glance: ideal, warning, or critical • Trend arrows show which way every parameter is moving • Smart suggestions — like testing sooner when alkalinity is dropping fast

KNOW YOUR LIVESTOCK • Snap a photo and let on-device AI suggest what fish, coral, or invert you're looking at — no account needed, photos never leave your phone • Keep a visual gallery of everything in your tank • Track each inhabitant's health history over time

DOSE WITH CONFIDENCE • Calculators for two-part alkalinity and calcium, magnesium, and trace elements with popular product presets • Large corrections are automatically split across days at reef-safe rates • Save doses to your log and schedule daily dosing reminders

YOUR TANK'S STORY • A timeline of milestones, water changes, treatments, and livestock — built automatically as you log • Add your own events with photos • Share your tank's journey as a beautiful story-format image

NEVER MISS MAINTENANCE • Reminder templates for weekly testing, water changes, and dosing • Snooze or complete with a swipe • See what's due right on your dashboard
