ReefDose - Dosing Calculator

Your reef chemistry is too important for a spreadsheet. Track every parameter, get exact doses in seconds, and catch problems before they become crashes.

Reef problems start in the water, before you see them in your coral.

ReefDose gives you a dosing calculator, 19-parameter tracker, Reef Health Score, and full reef management in one app. Built for SPS, LPS, nano reefs, frag tanks, quarantine systems, and multiple aquariums.

DOSING CALCULATOR

Take the guesswork out of reef dosing. Enter your tank volume, current test result, and target value to get the exact milliliters to add.

• Alkalinity (dKH) • Calcium • Magnesium • Two-part systems • Kalkwasser • All-in-one supplements • Trace elements • Custom supplements • Stock solution dosing • Dosing inventory tracking • "Runs out in" predictions

WATER PARAMETERS

Track 19+ reef parameters in one organized log:

Alkalinity, calcium, magnesium, pH, salinity, temperature, nitrate, phosphate, ammonia, nitrite, potassium, iodine, iron, strontium, ORP, PAR, TDS, and custom parameters.

Review your full history, monitor target ranges, and use trend charts to understand how your water chemistry shifts over time.

REEF HEALTH SCORE

ReefDose calculates a live Reef Health Score from your tracked parameters. See whether your chemistry is stable, drifting, or needs attention before it costs you coral.

Includes parameter status monitoring, insights, dosing history, and a full tank activity timeline.

MAINTENANCE AND TASKS

Set recurring reminders for every routine:

• Water changes • Water testing • Dosing • Top-offs • Filter cleaning • Media replacement • Equipment maintenance

LIVESTOCK AND EQUIPMENT

Log corals, fish, and invertebrates with species names, dates, photos, notes, and loss records. Track equipment with service dates and maintenance history.

JOURNAL, TIMELINE, AND ACHIEVEMENTS

Your tank journal captures observations, placements, and important events. The timeline shows every test, dose, livestock addition, and task in chronological order.

Build consistency with reef-keeping achievements and streaks.

MULTIPLE AQUARIUMS

ReefDose Pro supports unlimited tanks. Each display tank, frag tank, quarantine system, or nano reef gets its own parameters, dosing products, tasks, livestock, expenses, journal, and reports.

ICLOUD, WIDGETS, AND APPLE INTEGRATION

Private iCloud sync keeps your reef data on iPhone, iPad, and Mac. Included with Pro at no extra charge.

Home Screen widgets show live reef health and parameter status without opening the app. Siri Shortcuts and Spotlight search are also supported.
