Never forget water changes or filter swaps
Manage all your tanks from one dashboard
📝You test your water, jot down numbers somewhere, and then... forget where you wrote them.
💀You wake up to a bleached coral and have no idea what went wrong.
😵You spend hours researching why your ALK keeps dropping—only to get conflicting advice from five different forums.
💸You've lost fish. You've lost corals. You've lost money. And sometimes, you've lost the joy that got you into this hobby in the first place.
It doesn't have to be this hard.
Reef Track replaces scattered notes, forgotten logs, and guesswork with a single, smart hub for your entire reef journey.
See trends in your parameters over days, weeks, and months. Reef Track highlights when ALK is drifting or NO3 is creeping up—so you can act before corals suffer.
Set reminders for water changes, filter swaps, and dosing checks. Log maintenance in seconds from your phone. Build consistency without the mental load.
Log when you got it, where it's placed, photos over time, health notes, and more. When something goes wrong (or right), you'll have the history to understand why.
Running multiple tanks? Reef Track keeps them organized with a clean, at-a-glance dashboard showing what needs attention today.
Snap a photo of your livestock and let Reef Track suggest IDs, care notes, and tracking tags. Try it on the Free plan with limited uses, or upgrade for more.
Track your pumps, lights, heaters, and more. Log purchase prices, maintenance history, and see your investment in each piece of gear. Know exactly what you've spent and sold.
No complicated setup. No learning curve. Just add your tank and start logging.
Enter your tank's basics—size, type, start date. That's it. You're ready to go.
Record test results, add livestock, snap photos, log maintenance. Quick entries from your phone.
Reef Track analyzes your data and alerts you when something needs attention.
From nano tanks to fish rooms, hobbyists are finally getting their reefs under control.
"I have a 20-gallon AIO and thought I didn't need an app. Turns out, seeing my parameters graphed over time helped me finally beat my dino problem. Worth it even on the free plan."
"I've lost thousands in SPS over the years to random crashes. Since using Reef Track, I caught an ALK swing early and saved my whole colony. Pays for itself in one save."
"I've been in this hobby 15 years and kept logs in notebooks, spreadsheets, you name it. This is the first app that actually sticks. Simple, fast, and I actually use it."
"I recommend Reef Track to customers all the time. When they come back with problems, the ones logging in the app can actually show me data—makes diagnosing issues so much faster."
Start free. Upgrade when you're ready. Either way, it costs less than one dead coral.
Start tracking your reef with no commitment.

Keep testing, scribbling numbers, forgetting what you logged last week. When something dies, you're left guessing. The anxiety stays. The hobby feels harder than it should.
Your parameters are tracked. Trends are visible. You catch the ALK drop before it matters. Your corals grow. Your fish thrive. You actually enjoy looking at your tank.
