The biggest expansion in Reef Trak history

Reef Trak started as a reef tank app, and that is still its heart. But a huge number of reefers also keep a freshwater tank, a planted aquascape, a shrimp tank, or a quarantine setup, and they have been asking for one place to track all of it. Version 2.3.0 delivers exactly that. Freshwater community and planted aquariums now live right alongside your reef tanks, inside the same app, with the same syncing, the same photo tools, and the same attention to detail.

When you add a tank, you now choose its type. From that point on, Reef Trak adapts itself to match. It adjusts the parameters it tracks, the livestock you can add, the maintenance tools it offers, the recommendations it makes, and even its appearance. A freshwater tank feels like a freshwater app. A reef tank stays exactly the reef experience you already know.

Freshwater has arrived

Freshwater support is not a token mode bolted onto the side. It is a full, first-class system that touches nearly every part of the app.

  • 1,342 freshwater fish with compatibility checking, care information, photos, and scientific names
  • 129 aquatic plants with dedicated pages and growth-photo timelines
  • 48 freshwater invertebrates, including shrimp and snails
  • Freshwater foods, dosing products, maintenance templates, feeding logs, filter maintenance, and conditioner calculations
  • Freshwater-specific parameters, ideal ranges, cycle guidance, and guided testing

A freshwater fish catalog built the right way

The new freshwater fish catalog covers 1,342 species, browsable by family with the friendly common name on top and the scientific name underneath. Each fish carries care information and photos, so adding stock is catalog-first rather than free typing, the same way reef livestock already works in Reef Trak.

Compatibility checking comes along for the ride. As you build out a community tank, Reef Trak can flag combinations that tend to cause trouble, which is exactly the kind of early guidance that saves a new fishkeeper from an expensive mistake.

Aquatic plants and invertebrates

Planted-tank keepers get 129 aquatic plants, each with its own detail page and a growth-photo timeline that mirrors the coral growth tracking reefers already love. Watching a carpet fill in over months is just as satisfying as watching an SPS colony encrust.

There are also 48 freshwater invertebrates, including the shrimp and snails that anchor so many modern freshwater tanks. Whether you keep a dedicated shrimp tank or just a cleanup crew, they are now part of the catalog.

Freshwater care, feeding, dosing, and testing

Day-to-day tank care is fully freshwater-aware. Maintenance templates, water-change and top-off quick logs, a conditioner and dechlorinator calculator, feeding logs, and filter-maintenance logging are all tuned for freshwater workflows instead of reef ones.

Testing is freshwater-aware too. Reef Trak tracks a freshwater-specific parameter set with the right ideal ranges, supports drop-count entry for KH and GH style kits, and offers cycle guidance so newer aquarists understand what is happening as a fresh tank matures. The freshwater dosing catalog adds products meant for planted and freshwater systems, gated so reef-only goals do not clutter the experience.

Released a little like an open beta

Freshwater is a massive addition, and it touched nearly every part of Reef Trak. It has been extensively tested, but a change this large benefits enormously from real tanks and real users. So this is going out a little like an open beta.

If you find anything that is incorrect, confusing, or broken, please submit a bug report. The same goes for existing reef features. If something worked before this update and suddenly does not, I need to know about it. Fast feedback is how this gets polished quickly.

Reef Trak now supports 27 languages

Version 2.3.0 also ships the largest language expansion in Reef Trak history, and the entire new freshwater system is localized right along with everything else. Reef keeping and fishkeeping are global hobbies, and the goal is for the app to feel native no matter where you are.

Supported languages now include English (US), English (UK), Czech, Danish, German, Greek, Spanish, Finnish, French, Hungarian, Indonesian, Italian, Japanese, Korean, Norwegian, Dutch, Polish, Portuguese, Romanian, Slovak, Swedish, Thai, Turkish, Ukrainian, Vietnamese, Simplified Chinese, and Traditional Chinese.

More power on the Web Portal

Reef Trak is not limited to your phone or tablet. The Web Portal lets you reach your aquarium information from a desktop or laptop browser, which gives you a much larger workspace for reviewing trends and entering data without constantly reaching for your phone.

With 2.3.0, you can now import ICP reports directly through the Web Portal. Upload the original PDF or paste the report URL, and Reef Trak processes the results and automatically detects the test date. If you have not visited the Web Portal in a while, this is a great moment to take another look.

Better ICP imports everywhere

ICP importing has been rebuilt around a faster and more reliable server-powered system that works the same way across the app and the Web Portal.

  • Import by PDF or report URL through the app or Web Portal
  • Improved support for major ICP testing laboratories
  • Automatic report-date detection
  • Numerous laboratory-specific parsing and conversion fixes
  • Older on-device OCR removed for a smaller, more reliable app

Additional improvements

  • Premium purchases restore more reliably across devices
  • Existing users can launch the Cycle Assistant after adding a tank
  • Manufacturer information automatically fills for known tank models
  • Fixed missing Apex Fusion calcium probes labeled "Cal"
  • Reduced duplicate Apex endpoint entries
  • Fixed an iOS migration crash related to freshwater support

Final note

Thank you for helping test Reef Trak 2.3.0. Freshwater is a major expansion, and your bug reports will help me polish it quickly. Whether you keep a reef, a planted tank, a community tank, or all three, the goal is the same: one app that understands your water. Love Your Reef, Trak it.
