AquaLog: Aquarium Tank Tracker

NEW: AI Smart Diagnostics analyses symptoms against your live water data and surfaces the most likely cause in seconds. Update now to test it free this week.

AquaLog turns aquarium keeping into a calm, confident routine. Whether you run a planted nano, a community freshwater tank, a shrimp colony, or a full reef setup, AquaLog gives you one beautiful place to record water parameters, schedule maintenance, manage livestock, and catch problems before they hurt your fish.

WHY HOBBYISTS CHOOSE AQUALOG

A clean log instead of messy spreadsheets. Smart reminders instead of guessing when you last did a water change. A built in species library instead of bookmarked forum threads. AquaLog is the all in one companion your tank has been waiting for, designed by aquarists for aquarists, with every screen built around the rhythm of a real fishroom.

KEY FEATURES

Water Parameter Logging Record 13 vital parameters in seconds: temperature, pH, ammonia, nitrite, nitrate, GH, KH, salinity, TDS, calcium, magnesium, alkalinity, and phosphate. The smart keypad and step controls make daily logging effortless, and one tap reuses your last values when little has changed.

Beautiful Trend Charts View 30, 90, or 365 day curves for every parameter. Overlay multiple readings to spot the real story behind algae blooms, cloudy water, or stressed livestock. Out of range values are highlighted so issues never slip past you, and event markers let you correlate every spike with a water change, dose, or new arrival.

Smart Maintenance Calendar Set recurring tasks for water changes, filter cleaning, CO2 swaps, plant trimming, and feeding. Trigger based alerts fire when nitrate or temperature drift out of safe ranges. One tap marks a task done and writes the entry to your log automatically.

Inhabitant Library Track every fish, shrimp, snail, and coral with photos, growth notes, origin, and cost. Tap into a curated database with thousands of species, each with preferred parameters and compatibility hints, so stocking decisions stop being guesswork.

Equipment Tracker Log your filter, heater, light, pump, and CO2 gear with warranty dates and replacement reminders. Never overshoot a bulb life or forget a worn out impeller again.

AI Smart Diagnostics Choose symptoms, attach a photo, and AquaLog compares against your current water chemistry to suggest likely causes, treatment steps, and prevention tips. It is the calm second opinion you wish you had at 2 AM.

Multi Tank Support Manage multiple tanks side by side with independent data, photos, and reminders. Perfect for hobbyists with a planted display, a quarantine tank, and a shrimp colony all running at once.

Offline First Take readings next to the tank without worrying about signal.

Calm and Beautiful Design A clean ocean inspired interface with deep blue and seafoam accents. No clutter, no ads, no distractions, just clarity that respects the peaceful nature of the hobby.
