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. ONE ACCOUNT, EVERY DEVICE Your log is stored in your AquaticLog account, not on your phone. Sign in on a new iPhone, an iPad, or the web at aquaticlog.com and everything is already there. Aquarists have trusted AquaticLog with their records for over 13 years. Swipe between aquariums right from the main tank view. Keep one or several tanks visible on your iPhone Home Screen with configurable widgets. WATER PARAMETERS Log pH, temperature, ammonia, nitrite, nitrate, phosphate, salinity, alkalinity, calcium, magnesium and more. 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. Select and delete multiple inaccurate or duplicate readings from a parameter’s history in one step. LIVESTOCK AND PLANTS Build a detailed record of every fish, coral, invertebrate, plant and amphibian you own. Snap a photo 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 count, and see your maintenance time per day and 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 and share your progress or ask for help on the community forum. ADVANCED TESTING Log ICP water analyses and PAR light readings to fine-tune even the most demanding reef. Track test-kit reagents: every logged test counts one down, and the app warns you before a kit runs dry. 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 Search public tanks by what actually lives in them — look for a torch coral in the 15-30 gallon range and see how other nano reefs are scaped. Filter by tank style (mixed reef, SPS, LPS, soft coral, planted, macro algae, fish only), size, water type and recent activity, and open any tank to see its photos, parameters, gear and livestock. Browse a growing database of species and products, read and write reviews, like and comment on photos, and earn achievements as you go. Make your tank public to share its link, or copy a snapshot of its parameters, livestock and gear when asking for advice. Available in 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 — then upgrade to Pro for advanced tracking and tools. The yearly plan starts with a 7-day free trial. Get a daily AI suggestion based on your aquarium’s inhabitants, readings and care history.
