Reef Tank Pro is an intuitive way to track your aquarium on an iOS device. A unique concept allows you to select a tank and work exclusively with a specific task. Other aquarium management apps require you to run multiple tests at the same time where Reef Tank Pro gives you the ability to quickly access a specific tank and perform a specific test.

"There’s plenty of online tank loggers but Reef Tank Pro is one of the first polished apps we’ve seen…",

Reef Tank Pro does not currently sync between devices.

Many common measurements and activities are built into Reef Tank Pro. If a specific activity or measurement does not exist, you can create a personalized one as well add quantities and custom measurement units. In this way Reef Tank Pro can be used to suit your individual needs.

Reef Tank Pro includes the following built-in tests: Ammonia, Calcium, Carbonate Hardness, Magnesium, Nitrate, Nitrite, Phosphate, Specific Gravity (Salinity), Temperature, Total Dissolved Solids and pH

Reef Tank Pro allows you to associate a photo with your tank. The app provides the ability to take pictures of your test kits and test results for a more personalized view of your tank(s). Take actual photos of your test results and visually compare them.

The Log provides a chronological view of the data you have entered in a scrollable list. Each tank that you add can be viewed independently. In addition to tracking a reef tank, you can track the water parameters of tap water, RODI top off water, saltwater changes, refugiums and freshwater tanks.

Stats provides graphing for log entries. Graphs are plotted individually or by comparison. Graphs support one or more tanks and one or more entry types. The graphs support pinch to zoom.

Every screen in Reef Tank Pro supports both portrait and landscape orientations.

Ratings and Reviews

OK app


There are no instructions on how to use this app. The app is OK but needs a lot more work to even make it worth while. It's basically a excel spreadsheet in a app form. Bad purchase in my end. Save your money and go with an app that is an it more user friendly.

Bad app


No way to manually input the information for water test readings

Great app


I use this app and it is great. I am able to graph and log in all my water parameters. Helps to keep me testing that water, even when I don't feel like it. One issue that I have, when opening the stats menu to view my graphs, the app crashes. After multiethnic attempts it will finally let me in to view my graphs. Other than that, this app is a wonderful, user friendly way to log my tanks status through time. Some updates that I would hope to see are live stock additions, hardware additions such as skimmer or refugium, etc.
