Built by Reef Keepers, for Reef Keepers

The Problem

Reef keeping is chemistry. Successful reef keepers test their water regularly, track trends, and make data-driven decisions about dosing and maintenance. But the tools available were frustrating:

• Spreadsheets work, but they're tedious to update from a phone while standing at the tank
• Paper logs get lost, can't show trends, and are hard to analyze
• Generic apps don't understand reef chemistry or the specific parameters we care about
• Controller apps only show what the controller monitors—not your test kit results or ICP data

The Solution

ReefTanker is a purpose-built tool for reef keepers who care about data. It's designed around how we actually test and maintain our tanks:

• Mobile-first - Log parameters in seconds, right at the tank
• Reef-specific - Tracks the 8 parameters that matter, with sensible defaults for targets
• ICP integration - Upload lab reports and automatically parse 60+ elements
• Apex sync - Connect your controller to eliminate manual entry for monitored parameters
• Action logging - Document dosing, water changes, and equipment changes
• Multi-tank - Manage all your tanks from one account

Our Philosophy

We believe in data-driven reef keeping. Not chasing "perfect" parameters, but understanding your tank's patterns and making informed decisions. The best parameter is a stable one.

We also believe in keeping things simple. ReefTanker does one thing well: tracking your reef chemistry. No social features. No marketplace. No bloat. Just the tools you need to succeed.

Built With Care

Every feature in ReefTanker was designed with reef keepers in mind. We sweat the details:

• Touch targets sized for wet fingers
• Quick input flows for logging at the tank
• Color-coded status indicators (in-range, warning, critical)
• Charts that show trends at a glance
• ICP parsing that actually works
