AquaticLog vs ReefATLAS PAR Estimator

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.

ReefATLAS PAR Estimator is a subscription-based aquarium lighting analysis app built for reef keepers who want a smarter way to estimate light levels without always having access to a PAR meter. Designed for reef aquarium hobbyists and professionals, ReefATLAS PAR Estimator helps predict and visualize PAR distribution using tank dimensions, lighting equipment, mounting height, spectrum settings, fixture intensity, water conditions, lid transmission, surface agitation, and other key variables. The goal is simple: help reef keepers make better lighting and coral placement decisions before guessing, moving coral blindly, or copying someone else’s lighting schedule from a different setup. FEATURES • Interactive 3D PAR heatmap visualization • Support for popular reef aquarium lighting systems • Multi-fixture light array setup • Fixture placement using a top-down tank layout • Support for mixed light models in the same setup • Individual fixture height, position, rotation, and angle controls • Master/slave light grouping for linked fixtures • Spectrum and intensity adjustment tools • Manufacturer-style spectrum presets where available • Custom tank dimension configuration • Manufactured tank catalog support • Glass thickness and internal dimension calculations • Surface agitation / shimmer adjustment • Lid type and lid cleanliness modeling • Salinity-aware estimate adjustment • Project save and load functionality • Local device-based project storage • Optimized for reef aquarium planning and coral placement SUPPORTED LIGHTS ReefATLAS PAR Estimator includes modeled profiles for many popular reef lights, including AquaIllumination, EcoTech Marine, Kessil, Red Sea, ReefBreeders, Maxspect, Fluval, Illumagic, REEFi, Orphek, Philips CoralCare, NavaReef, Noo-Psyche, GHL, Current USA, and more. View the current supported light list here: https://thereefatlas.com/par-estimator-lights New lights and tanks are added regularly. If your light or tank is not listed, the app includes request buttons so you can send it in for review. Requested lights are prioritized for modeling when enough manufacturer/spec/PAR reference data is available. HOW IT WORKS Configure your aquarium dimensions, select your lighting equipment, adjust fixture placement, mounting height, spectrum, intensity, water conditions, and lid settings, then generate a 3D PAR distribution estimate throughout the aquarium. For single-light setups, quickly model one fixture over your tank. For advanced systems, the Light Setup tool lets you place multiple fixtures across a top-down tank grid, including mixed models, different mounting heights, fixture rotation, and angled mounting. The estimator calculates each fixture’s contribution at each point in the aquarium and combines overlapping light output to create the final PAR estimate. This helps represent real-world multi-light setups where beams overlap, spread, and converge across the tank. IMPORTANT ACCURACY NOTE ReefATLAS PAR Estimator is an estimation tool. A real PAR meter will always be the most accurate option for measuring your specific tank. However, many reef keepers do not have access to a PAR meter. This app is designed to provide a better starting point than guessing by combining modeled light profiles, tank dimensions, fixture placement, spectrum settings, mounting height, water depth, lid transmission, salinity, and surface agitation into one interactive estimate. Accuracy depends on available fixture data, setup inputs, and real-world variables such as rockwork, coral shading, water clarity, lens condition, and surface movement. SUBSCRIPTION REQUIRED ReefATLAS PAR Estimator requires an active monthly subscription to access and use the app. A subscription purchase is required to use the PAR estimation tools and features shown in the App Store screenshots and description.
