Built by Aquarists, for Aquarists

AquaMetrics is a comprehensive, free tank management platform created by hobbyists who couldn't find the all-in-one solution they needed.

🌊 Our Story

As long-time aquarium enthusiasts and software developers, we spent years juggling spreadsheets, phone notes, calendar reminders, and multiple apps to manage our tanks. We tracked water parameters in one place, maintenance schedules in another, and referenced care guides scattered across dozens of websites and forums.

We looked for a single platform that could do it all—track parameters with beautiful charts, send smart alerts, manage maintenance schedules, provide reliable care guides, and work seamlessly across all our devices. It didn't exist.

So we built it ourselves. AquaMetrics combines everything an aquarist needs into one cohesive, intuitive platform. And because we believe every hobbyist deserves access to great tools regardless of budget, it's completely free—and always will be.

We're constantly improving AquaMetrics based on community feedback. We review every feature request and suggestion we receive, and many of our best features came directly from users like you. Have an idea? Submit a suggestion and help shape the future of AquaMetrics!

📊 Complete Parameter Tracking

🧪

Comprehensive Parameters

Track every parameter that matters for your specific tank type:

  • Saltwater: pH, Alkalinity, Calcium, Magnesium, Nitrate, Phosphate, Salinity, Temperature
  • Freshwater: pH, Ammonia, Nitrite, Nitrate, GH, KH, Temperature
📈

Visual Trends & Analytics

Beautiful, interactive charts show your parameter history at a glance. Spot trends, identify patterns, and understand your tank's stability over days, weeks, or months.

🎯

Custom Target Ranges

Set personalized target ranges for each parameter based on your tank's specific needs. What works for an SPS-dominant reef differs from a fish-only system.
