AquaticLog keeps water parameters, livestock, equipment and care routines together for every freshwater tank and reef. ONE ACCOUNT, EVERY DEVICE Your log lives 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. Keep your tanks on the iPhone Home Screen with widgets. WATER PARAMETERS Log pH, temperature, ammonia, nitrite, nitrate, phosphate, salinity, alkalinity, calcium, magnesium and more. Clear trend charts let you catch a swing before it reaches your fish or corals. Connect a Neptune Apex, Hydros, AquaWiz or Seneye for hourly readings, including Seneye NH3 and NH4. Delete bad readings in batches and schedule retests for out-of-range results. LIVESTOCK AND PLANTS Build a detailed record of every fish, coral, invertebrate, plant and amphibian you own. Add a photo as you add a new fish or coral. Track sex, temperament, diet, difficulty and reef-safety, and move inhabitants between tanks as your collection grows. Tank birthdays and gotcha days share a card you can dismiss. MAINTENANCE MADE SIMPLE Schedule water changes, dosing, feeding, testing and equipment cleaning. Smart reminders make sure nothing slips. Check off a task and it lands with a haptic; once nothing is due, your tank shows what's next. A daily streak beside Reminders rewards showing up. End a repeating schedule on a date or after a set count, and see your maintenance time per week. Service accounts can start client visits and finish them with notes and next-visit plans. DOSING AND FEEDING Track dosing and feeding with a precise history. Log feeding every 48 hours or at another fixed interval. Re-dose additives, repeat feedings and repeat water changes in one tap, prefilled with your last amounts. Repeated doses and feedings fold into one row per day. FISH ROOM AND WATER CHANGES Set up RO/DI with SpectraPure, BRS and Waterbox presets. Track filter changes and TDS for each membrane and DI stage. Manage supplies and spending in Fish Room, with INR support. PHOTO TIMELINE Track growth and coloration. Then vs Now slides between your first photo and your latest, with dates and tank age. Pinch to zoom. Start a build thread for your tank on the community forum and post what changed as it grows. ADVANCED TESTING Log ICP analyses and PAR readings. ICP warnings stay grouped; dismiss individual results and restore them anytime. Share test-kit reagents across tanks in Fish Room: logged tests count supplies down, with fill levels and days left. EQUIPMENT Track pumps, lights and filters, with ratings and reviews. Browse products by category or brand, see which tanks use them, and add them to your tank or shopping list. A spending report totals what you've paid per store, filterable by tank and date range (Pro). EXPLORE AND CONNECT Search public tanks by what lives in them — look for a torch coral in the 15-30 gallon range and see how other nano reefs are scaped. Filter by style (mixed reef, SPS, LPS, soft coral, planted, macro algae, fish only), size, water type and activity, then open any tank to see its photos, parameters, gear and livestock. Find Today, Aquariums, Species, Products and News together in Explore. Read reviews, like photos and earn achievements. Make your tank public to share its link, or copy a snapshot of its parameters, livestock and gear to ask 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 30 days — then upgrade to Pro for advanced tracking and tools. The yearly plan starts with a 7-day free trial. Get daily AI suggestions based on tank data and see when each was generated.
