Reef Trak - Reef Manager

Reef Trak pioneered ICP testing, multi-controller imports, and many reef-keeping firsts—innovations now shaping the next generation of aquarium apps.

Reef Trak is an all-in-one reef tank manager for reef keepers who want more than a basic parameter log.

Track water parameters, plan dosing, schedule maintenance, manage livestock, save photos, build PAR maps, import controller data, track expenses, and create reports across iOS and the web.

Build a complete reef care history, then export real tank data to AI tools with TrakAI.

FREE TO START. ONE-TIME PREMIUM UPGRADE. Reef Trak includes a free version with parameter tracking and core reef tank tools. Reef Trak Premium is available as a one-time upgrade. No monthly subscription. No yearly subscription. Pay once and use Premium tools without another recurring app bill.

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 Plan and track two-part, All-For-Reef, kalkwasser, trace elements, supplements, and custom routines. Use manual and guided dosing tools, bottle tracking, dose logging, reminders, and parameter connections to keep dosing tied to your real tank history.

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 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.

Reef Trak is actively developed with frequent updates shaped by the reefkeeping community.
