About Aquarium Log: Water Tracker
▶ Better aquarium care starts with understanding what is happening in your tank. Aquarium Log helps you track water parameters, maintenance, notes, and reminders — all in one place. ▶ Know How Your Tank Is Doing See your latest water readings, recent activity, and upcoming maintenance at a glance. Each aquarium can be configured separately, so you only track the parameters that actually matter for that tank. ▶ See Trends, Not Just Numbers Follow pH, temperature, nitrate, and other parameters over time. View trends across 7 days, 30 days, 3 months, 1 year, or your full history — with the latest, minimum, maximum, and average values. Water changes, cleaning, dosing, and notes can also appear alongside your charts, helping you understand what happened before and after a change. ▶ Keep a Clear Maintenance History Record water changes, filter cleaning, tank cleaning, fertilizing, plant trimming, equipment service, and your own custom maintenance. Everything is organized chronologically, so you always know what was done — and when. ▶ Don’t Rely on Memory Create reminders for water tests, water changes, filter cleaning, fertilizing, or any recurring task. Complete, snooze, or skip a task while keeping your routine on track. ▶ Record What Numbers Can’t Tell You Add notes about fish behavior, plant growth, algae, unusual changes, or anything else you want to remember. Combining observations with test data gives you a more complete history of your aquarium. ▶ One App for Every Tank Manage multiple aquariums independently — from freshwater and planted tanks to shrimp, reef, or custom setups. Each tank keeps its own parameters, history, notes, and reminders. ▶ Keep Your Data in Your Hands Export your records as CSV or create a full backup of your aquarium data whenever you need it. Aquarium Log helps you remember less, understand more, and care for your aquarium with greater consistency. ▶ Know what changed. Know what was done. Know what’s next.
