## What is ReefLog?

ReefLog is a local-first logbook for reef and saltwater aquarium keepers. Record water parameters, review trends, estimate dosing changes, and organize recurring care—all in one focused tracker.

LOG WATER PARAMETERS
Track alkalinity, calcium, magnesium, salinity, nitrate, phosphate, pH, temperature, and more. Choose the parameters that matter to each tank, then use Quick Log to add readings and see recent values and target ranges.

SEE TRENDS OVER TIME
Review charts across weekly, monthly, and longer periods. Edit or backdate readings when needed and keep your log accurate.

KEEP TANK CARE ORGANIZED
Manage Reef, Saltwater, and Fish Only tanks. Schedule water tests, maintenance, and equipment care. Optional local reminders help keep recurring tasks on track.

RECORD DOSING
Estimate dosing changes based on tank volume and readings, record each dose, and track products and bottles with safety checks. ReefLog does not control dosing equipment.

OPTIONAL REEFLOG PRO
ReefLog Pro adds multiple tanks, advanced parameters, unlimited dosing products and bottles, and manual Cloud Backup creation and restore.

LOCAL-FIRST BY DESIGN
Use ReefLog without an account for normal local logging. Your data stays on your device unless you choose Cloud Backup. Cloud Backup requires sign-in and is a manual backup, not live sync. Export CSV or create a local JSON backup. No ads or analytics.
