Reef Master

Reef Master — Reef Tank Manager
Keep your reef aquarium healthy, organized, and easier to maintain with Reef Master.

Reef Master brings your tank’s most important information into one simple mobile app. Track water parameters, monitor trends, manage livestock, stay on top of maintenance, and get practical AI-powered guidance based on your tank.

Monitor your reef at a glance
See your tank health in one clear dashboard with:

Overall tank health score
Latest parameter readings
In-range and out-of-range indicators
Ideal parameter ranges
Alerts for readings that need attention
Standard and advanced ICP parameter views
Last-updated reading information
Log water parameters easily
Record readings manually whenever you test your aquarium. Reef Master helps you keep a consistent history of important measurements such as temperature, salinity, pH, alkalinity, calcium, magnesium, nitrate, phosphate, and other reef parameters.

You can customize ideal minimum and maximum ranges for your tank and display measurements using your preferred temperature and salinity units, including Celsius, Fahrenheit, specific gravity, and parts per thousand.

View trends and history
Understand how your reef is changing over time with visual charts and detailed reading histories. Review the last 7, 14, 30, or 90 days, switch between line and bar charts, zoom in on data points, and see which readings were in range or triggered an alert.

Add notes to individual readings so you can remember what happened after a water change, dosing adjustment, equipment change, or livestock addition.

Use smart photo tools
Save time during testing with image-powered tools:

Scan a test kit photo and review detected readings before saving them
Import readings from a SmartReef screenshot
Check and edit extracted values, dates, and times before logging
Correct earlier screenshot imports when the original reading details need repair
All extracted readings can be reviewed before they are added to your tank history.

Manage tanks and livestock
Create and manage one or more reef tanks with details such as:

Tank name and description
Volume
Brand and model
Equipment list
Tank photo
Active or archived status
Keep track of fish, corals, and other aquarium inhabitants, including useful care details and individual notes. Maintain a clearer picture of what lives in each tank and how your reef is developing.

Stay on top of maintenance
Create recurring aquarium tasks for testing, feeding, cleaning, maintenance, water quality, inspection, and treatment. Set schedules such as daily, weekly, monthly, quarterly, or as needed.

See tasks that are due, mark completed work, edit reminders, and keep routine maintenance from being forgotten. Reef Master can also support cycling reminders when setting up a new tank.

Ask the Tank Assistant
Get AI-powered help with reef-keeping questions, water parameters, coral care, tank health, maintenance, and troubleshooting. You can ask questions using text and, where supported, include a photo for additional context.

The assistant can also suggest useful maintenance tasks based on your conversation, helping turn advice into an actionable reminder. Save and revisit previous conversations whenever you need them.

Reef Master Pro provides access to premium AI features, including AI chat and reef reports, through optional in-app purchases.

Reef Master is built to help you make better decisions by keeping your aquarium records, observations, livestock details, and maintenance schedule together in one place.

Whether you are setting up your first marine aquarium or maintaining an established reef, Reef Master helps you build better habits and spot changes before they become bigger problems.

Reef Master provides informational guidance and tracking tools. AI suggestions are not a substitute for professional aquatic, veterinary, or scientific advice. Always use your own judgment and follow the instructions provided with aquarium products and test equipment.
