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.

It's ok

For 5 bucks I expected a lot, I'm a little let down. The interface is not intuitive, although once you've used it for awhile it's easy enough. My biggest complaint is that you can (after much effort) export your data as a .csv file but can't import that file into the same app on a different devise. I use my iPad at home to record my system's parameters but would like to have my data available on my iPhone when I'm on the go.

Great App

I’ve been using reef tank pro for about two years and keep records on three tanks. The thing I like most about the app is you can create custom types of data. As an example, I’ve created an entry for equipment purchases, equipment maintenance, fish purchases, water changes etc. you just have to use your imagination.

Great app

New to reefing and this app definitely helps keep all of my stuff logged. Really enjoy that you can create your own entrees as I get new fish, new coral, products etc. I keep everything tracked in here. Really makes everything easy to look back.
Worth the few bucks
