## What is AquaticLog?

AquaticLog is the complete companion for every aquarium you keep. Whether you run a single planted tank, a peaceful community aquarium, or a full-blown reef, AquaticLog helps you keep your water stable, your livestock thriving, and your routine on track.

Stop guessing and start knowing. Bring every reading, every photo, and every reminder together in one place.

Swipe between aquariums from the main tank view so checking each system stays quick.

Keep your chosen tank, or several tanks at once, visible from your iPhone Home Screen with configurable aquarium widgets.

WATER PARAMETERS
Log pH, temperature, ammonia, nitrite, nitrate, phosphate, salinity, alkalinity, calcium, magnesium and more, with notes captured alongside each result. Watch every reading on clear trend charts so you can catch a swing before it ever reaches your fish or corals. Connect a Neptune Apex, Hydros, AquaWiz or Seneye and supported readings flow in automatically every hour.

LIVESTOCK AND PLANTS
Build a detailed record of every fish, coral, invertebrate, plant and amphibian you own. Snap a photo with the camera the moment you add a new fish or coral, or pick one from your library. Track sex, temperament, diet, difficulty and reef-safety, and move inhabitants between tanks as your collection grows.

MAINTENANCE MADE SIMPLE
Schedule water changes, dosing, feeding, testing and equipment cleaning. Smart reminders make sure nothing slips, and a single tap logs the job as done. End a repeating schedule on a date or after a set number of doses or tasks. Add how long each task takes and see your maintenance time per day and per week.

DOSING AND FEEDING
Set up dosing and feeding programs, track supplements, and keep a precise history of exactly what went into your tank and when. Re-dose additives, repeat feedings and repeat water changes in one tap, prefilled with your last amounts.

WATER CHANGES AND RO/DI
Record every water change and keep an eye on your RO/DI output so your source water stays dialed in.

PHOTO TIMELINE
Document growth and coloration over time. Build a stunning visual history of each aquarium and share your progress with the community.

ADVANCED TESTING
Log ICP water analyses and PAR light readings to fine-tune even the most demanding reef.

EQUIPMENT
Keep a full inventory of pumps, lights, filters and more, with ratings and reviews to guide your next upgrade. Browse the product catalog by category or brand, see how many tanks run each product, and add one to your tank or shopping list straight from its page. A spending report totals what you've paid per store across livestock and equipment, filterable by tank and date range (Pro).

EXPLORE AND CONNECT
Browse a growing database of species and products, read and write reviews, follow fellow hobbyists, and earn achievements as you go.

AquaticLog speaks your language, with full support for English, German, Spanish, French, Italian, Dutch, Polish, Russian, Ukrainian and Brazilian Portuguese.

Start for free — new accounts log water parameters without limits for their first 30 days — and upgrade to Pro to unlock advanced tracking and tools. The yearly plan starts with a 7-day free trial.

Your tank deserves better than a notebook. Download AquaticLog and give every aquarium the care it deserves.

### 5/5 — Love this app!!!!

*2026-08-01*

I’ve tried quite a few reefing apps over the years and AquaticLog is hands down my favorite. It’s one of the few apps that I actually use every day. Everything is laid out well and it’s easy to log parameters, maintenance, livestock, dosing, and equipment without digging through a bunch of menus.

What really sets it apart is how often it’s updated. The developer is constantly adding new features and actually listens to feedback from the reefing community. It never feels like an abandoned app.

The controller integrations are awesome and make it easy to keep everything in one place. Being able to import and track ICP results is another huge plus. Having all of that information together makes it much easier to spot trends and keep your tank on track.

If you’re serious about reefing, I honestly can’t recommend AquaticLog enough. It’s become one of the most valuable tools I use to manage my tank.

### 1/5 — 10 measurements per month

*2026-06-29, version 15.2.0*

Limiting you to 10 measurements per month is ridiculous.

### 5/5 — Awesome app

*2026-06-10, version 15.1.1*

Great way to log your water test parameters

### 1/5 — What a joke

*2026-05-21, version 15.1.0*

After 2+ years of using Aquatic Log, now you have to pay for premium to log more than 10 things.

### 5/5 — Organized and great features

*2026-05-20, version 15.1.0*

Great app for chronicling an aquarium. I use it for both a FW and a reef tank. I like seeing the graphs of my parameters and being able to upload ICP tests. I tried a couple other apps but like this one the best by far. I do appreciate not being forced to see ads or urged to buy things. Such a relief. Get this one!

### 1/5 — Unhappy

*2026-05-19, version 15.1.0*

All of a sudden I have lost all my entries of inhabitants. Wasted 3 years of records to be told you have to pay me to keep seeing them.

### 5/5 — Track ALL your data

*2026-04-13, version 14.5.0*

Very customizable fields for aquarium testing. Can log almost everything - track livestock, maintenance activities, dosing and all testing results. It’s freaking great!

### 2/5 — Unable to update measurements

*2026-03-11, version 14.4.3*

I’ve been using the free version of this app for a few years & I’ve loved it. Now I suddenly can’t add more than 10 measurements per month?? Currently looking for another app after this update. Previously review would have been 4-5 stars.

### 5/5 — Exceptional app, responsive team

*2026-03-10, version 14.4.0*

I have used Aquatic Log for years across multiple tank configurations. It has consistently provided excellent functionality, with continual feature improvement, and responsive developer support. I recommend this app to both beginner and advanced aquarists.

### 5/5 — Excelente app

*2026-03-09, version 14.4.0*

Me gusta la app por qué me da detalles ayuda a tener recordatorios q tengo q realizar o checar y me da gráficas detalles como se ah comportado mi tanque marino
