## What is Recif?

Recif is the reef-keeping companion that turns every water test into something you can act on. Log your parameters, watch the trends, and follow one simple number, the Reef Stability Score, that tells you at a glance whether your tank is holding steady.

Built for saltwater and reef aquariums of every size, from a first nano to a room full of SPS.

REEF STABILITY SCORE
- One score from 0 to 100 that blends how many parameters are in range, how steady they have been, and how fresh your tests are
- See exactly what is driving your score and what to fix first
- Watch it climb as your tank settles in

LOG TESTS IN SECONDS
- Enter alkalinity, calcium, magnesium, salinity, pH, nitrate, phosphate and more
- A fast number pad and steppers tuned to each parameter
- Add a note or backdate a reading whenever you need to

CHARTS THAT MAKE SENSE
- Every parameter trended over time against its healthy range band
- Spot drift early, before it becomes a problem
- Press and hold to inspect any single reading

STAY ON SCHEDULE
- Water changes, dosing, testing, cleaning and top offs, all in one task list
- Recurring schedules and gentle reminders tuned to your tank
- Never miss a water change again

TRACK YOUR LIVESTOCK
- Keep a record of your fish, corals and inverts
- Mark what is thriving, struggling or lost, with notes and photos
- Learn what really works in your system

YOURS, EVERYWHERE

- Your whole reef history, backed up and on every device
- Choose your units: gallons or liters, Celsius or Fahrenheit, dKH, ppm or meq/L
