Track water parameters, livestock, dosing, maintenance, photos and notes — and keep a clear history for every tank.
REEFdesk helps reef and marine aquarium keepers keep every important detail in one place: water tests, livestock, dosing, maintenance tasks, photos, videos, and notes. Track parameters over time, spot trends before they become problems, and build a reliable history of your aquarium's progress.
Most reef keepers end up with test results in one app, photos in a gallery, dosing notes in a spreadsheet, and maintenance reminders somewhere else. REEFdesk brings those records together so you can understand what changed, when it changed, and what happened next.
A reef tank rarely changes because of one isolated value. A phosphate rise may follow heavier feeding. Alkalinity may drift after a dosing change. Corals may look different after a move, a water change, or a lighting adjustment. REEFdesk gives you the context around those events.
Log pH, kH, Nitrate, Phosphate, Calcium, Magnesium, and other key values. View trends by week, month, or all time so you can see how your aquarium responds to changes in dosing, feeding, and maintenance.
Keep a structured inventory of fish, corals, and invertebrates. Organize inhabitants by category, add photos, and record observations.
Review recent values, compare parameters, and browse the full measurement history for each test. REEFdesk turns scattered notes into clear, searchable aquarium data.
Store aquarium photos and videos with dates, captions, and tags. Build a visual timeline that makes it easy to compare coral growth, aquascape changes, and long-term progress.
Create a dashboard for each tank with the widgets you care about most: latest test results, upcoming tasks, tank photos, and parameter charts.
Schedule recurring tasks such as water changes, parameter checks, dosing, coral feeding, and equipment maintenance. See what is due next and mark tasks complete when they are done.
REEFdesk is built for the way aquariums are actually maintained: test, adjust, observe, and repeat. Each step leaves a record you can come back to later.
Add a new measurement for pH, kH, Nitrate, Phosphate, Calcium, Magnesium, Salinity, Temperature, or any custom parameter you track.
Switch between recent and long-term charts to see whether the value is stable, drifting slowly, or changing fast enough to need attention.
Note what you changed: dosing amount, water change, livestock move, coral feeding, equipment cleaning, or anything else that may explain the trend.
Create recurring tasks so routine maintenance does not depend on memory. When it is done, mark it complete and keep the history clean.
Clear charts and measurement history help you understand whether parameters are stable, improving, or moving in the wrong direction.
Tests, dosing, livestock, notes, media, and maintenance tasks are connected in one workflow instead of scattered across spreadsheets, reminders, and photo albums.
Use REEFdesk from your computer, tablet, or phone and keep your aquarium records available whenever you need them.
The goal is not to enter data for the sake of data. The goal is to make the tank easier to read when something looks different.
Keep routine test results readable and comparable.
Record the work that keeps the system stable.
Build a practical journal for fish, corals, inverts, etc.
