## What is ReefVitals?

ReefVitals turns your water test results into answers.

Most tank logs show you a number and leave you guessing. ReefVitals tells you what the number means — and exactly what to do about it.

REEF ASSISTANT
• Corrective dosing — enter your alkalinity, calcium, or magnesium reading and get the exact dose for your tank volume, calculated from real chemistry
• Safe by design — if a correction is too large to make at once, ReefVitals splits it across days so you don't shock your corals
• Water change planner — see what a 15% change does to high nitrate before you mix a drop of salt
• Drift detection — ReefVitals watches the trend and warns you days before a parameter leaves its ideal range

TRACK EVERYTHING THAT MATTERS
Temperature, salinity, pH, alkalinity, calcium, magnesium, nitrate, phosphate, ammonia, and nitrite — each with the accepted ideal range for a mixed reef built in.

AT A GLANCE
• Color-coded dashboard: in range, near range, out of range
• History charts with the ideal range drawn right on the graph
• Batch entry — log everything from one test session in one screen
• Test reminders so parameters never drift unnoticed

BUILT FOR REEF KEEPERS
• Works completely offline — no account, no sign-up
• Your data stays on your device. It is never uploaded, sold, or shared.
• Fast entry designed for wet hands and a test kit on the counter
