PARAMETERS
Track alkalinity, calcium, magnesium, nitrate, phosphate, salinity, temperature, pH, ORP, iodine, potassium, trace elements, and other reef tank parameters. Follow trends, spot drift, review stability, and see clear in-range or out-of-range indicators.

DOSING

MAINTENANCE
Create recurring tasks for water changes, filter swaps, probe calibration, dosing reminders, equipment checks, deep cleans, and custom care routines. Use weekly, fortnightly, monthly, yearly, every N days, or specific weekday schedules. Home screen widgets help show what is due today.

LIVESTOCK
Catalog fish, coral, and inverts with photos, care notes, acquisition history, tank placement, and long-term records.

PAR MAPS
Capture PAR readings across your reef tank and map them visually to understand coral placement, lighting coverage, and tank zones.

TRAKTONE PHOTO & VIDEO CORRECTION
Reef lighting can make photos and videos look far more blue than they appear in person. TrakTone helps correct reef tank photos and videos so corals, fish, and aquascapes look closer to what your eyes see.

EQUIPMENT, EXPENSES & RECEIPTS
Track equipment, food, dosing products, livestock purchases, maintenance costs, and other reef expenses. Receipt Scan Assist helps turn receipts into structured expense records.

CONTROLLER IMPORTS & ICP TESTING
Bring reef tank data into Reef Trak from supported controllers and testing systems, including Apex, Trident, and more. Track ICP results and keep lab testing connected to your tank history.

EMAIL UPDATES
Get reef-themed tank summary emails to stay connected to what is happening across your tanks, especially when managing multiple aquariums.

REPORTS & AI EXPORTS
Export parameter summaries, dosing logs, maintenance history, livestock notes, and other tank records in formats ready for ChatGPT, Claude, and other AI tools.

PRIVACY & DATA CONTROL
Your tanks are your data. Reef Trak does not run ads and does not sell reef hobbyist data. Your reef records are protected with encryption on your device and on our backend. Free CSV export lets you take your tank history wherever you need it.
