ReefGuy : Saltwater Tank

ReefGuy – Your Personal Reef Assistant

A saltwater aquarium is about more than individual measurements. ReefGuy helps you monitor your reef, understand trends, and simplify everyday aquarium care.

Water parameters, livestock, dosing, ICP tests, tasks, and backups – all organized in one place.

**TRACK YOUR WATER PARAMETERS**

Record measurements and follow their development with clear, easy-to-read charts. ReefGuy supports alkalinity (KH), calcium, magnesium, nitrate, phosphate, temperature, and salinity.

Water changes, maintenance, and livestock additions are displayed alongside your measurements, making it easier to understand changes over time.

**REEF SCORE**

The Reef Score combines water parameters, stability, maintenance, and available data into a clear overview of your aquarium's current condition.

**DOSING MADE EASY**

The integrated dosing calculator supports products from various manufacturers and helps calculate starting doses and necessary adjustments.

Create dosing schedules and distribute daily amounts across multiple doses and times. ReefGuy can also calculate alkalinity, calcium, and magnesium consumption from your recorded measurements.

**MANAGE AND ANALYZE ICP TESTS**

Import ICP reports and keep them organized with your aquarium.

ReefGuy can automatically analyze supported ICP reports and prepare detected values for your review, reducing manual data entry.

**PRACTICAL REEF TOOLS**

Calculate water changes, adjust salinity and salt quantities, or determine necessary nitrate and phosphate corrections.

Calculations are tailored to your aquarium's configured water volume.

**ORGANIZE YOUR LIVESTOCK**

Manage fish, corals, and other aquarium inhabitants. Add notes, photos, and documents to keep important information accessible.

**TASKS AND REMINDERS**

Schedule recurring maintenance and receive reminders for water testing, water changes, and your own aquarium care routines.
