AquaLens: Aquarium Log Tracker

Stop guessing what changed in your aquarium. AquaLens is an aquarium app that identifies fish, scans water tests, and turns everyday tank care into a clear history of water quality, dosing, maintenance, and health. Built for freshwater, saltwater, planted, reef, shrimp, breeding, quarantine, and multi-tank setups, this fish tank app combines an aquarium tracker, water test scanner, journal, care reminders, and tank-aware guidance. IDENTIFY FISH, PLANTS, CORAL, AND MORE Take a photo to identify fish, aquatic plants, coral, algae, shrimp, snails, and other aquarium life. Explore care requirements, preferred water parameters, diet, temperament, and compatibility before adding a new resident. AquaLens shows when an identification is uncertain instead of forcing an answer. SCAN WATER TESTS AND TRACK PARAMETERS Photograph supported test strips or liquid test kits, or scan supported digital testers with OCR. Review every reading before it saves, then add it directly to your aquarium journal. Track pH, ammonia, nitrite, nitrate, phosphate, temperature, salinity, alkalinity, calcium, magnesium, and more. KEEP A FISH TANK LOG THAT EXPLAINS WHAT CHANGED Record water changes, feeding, dosing, aquarium maintenance, livestock, notes, and photos in one timeline. When a parameter shifts, look back at what happened around it instead of relying on memory. SEE AQUARIUM HEALTH TRENDS Turn water tests into clear charts over time. Compare parameter changes with new livestock, dosing, and maintenance to spot patterns earlier. With AquaLens Pro, predictive alerts use your own tank history to flag movement toward unsafe ranges while the fix may still be small. PLAN STOCKING BEFORE YOU BUY Build an aquarium stocking wishlist and use the fish compatibility checker to compare adult size, temperature, water needs, temperament, group size, and estimated bioload. Plan your aquarium before spending money or bringing home a resident that does not fit. STAY AHEAD OF TANK CARE Create reminders for water tests, water changes, feeding, filter cleaning, dosing, medication cycles, and custom maintenance. Completed tasks can be added to your journal so your care routine stays useful, not just remembered. FRESHWATER, SALTWATER, PLANTED, AND REEF Manage multiple aquariums without mixing their histories. Follow cycling guidance for a new fish tank, use planted aquarium tools for freshwater setups, and track salinity, alkalinity, calcium, magnesium, dosing, ICP results, and coral placement for reef tanks. GUIDANCE THAT KNOWS YOUR TANK Ask AquaGuide aquarium questions. With Pro, answers can use your selected tank's parameters, residents, equipment, and history instead of offering generic advice. Visual health tools can flag possible concerns and provide educational next steps. AquaLens does not provide veterinary diagnosis or treatment.
