## What is Reefly?

KNOW YOUR REEF IS HEALTHY. IN SECONDS.

  ReefLog turns raw water test numbers into a clear tank health score - so you stop guessing and start knowing.

  Log your parameters, see instant colour-coded feedback (Good ·  Near limit · Out of range), and track trends over time. Whether you keep a
  saltwater reef, freshwater community, or planted aquarium, ReefLog gives your tank a grade every time you log.

-----------------------
  WHAT YOU CAN DO
-----------------------
- Log pH, alkalinity, calcium, magnesium, ammonia, nitrate, salinity and temperature
- See instant status feedback as you type — no guesswork
- View trend charts with safe-range bands so problems are visible before they become emergencies
- Set maintenance reminders — water changes, feeding, dosing — so nothing slips
- Works for reef, saltwater, freshwater, and planted aquariums

  TANK HEALTH SCORE
---------------------
  After every log session, ReefLog grades your tank (A+, A, B+…) based on how your parameters compare to proven safe ranges. One glance tells you
  everything.
