"I have a Google Sheet with 47 tabs and I still can't tell if my alk is trending down."

😤

"Downloaded 3 apps. One was Android-only, one got abandoned, the last one won't let me delete a wrong entry."

💸

"Lost $800 in SPS because I didn't notice my alk had been dropping for two weeks."

What ReefLog does differently

10-Second Logging

Log Ca, Alk, Mg, NO₃, PO₄, pH, salinity, and custom parameters faster than you can cap a test vial.

📈

Auto Trend Graphs

See problems before your coral tells you. Automatic charts show parameter trends over days, weeks, or months.

🔔

Smart Reminders

Test reminders, water change schedules, filter floss swaps, carbon replacement — never forget maintenance again.

🧪

Dosing Log

Track your 2-part, kalkwasser, or all-in-one dosing alongside parameters to see what's actually working.

📱

Works Everywhere

Phone, tablet, desktop. No app download needed — it's a web app that works beautifully on any device.

Reef tank, frag tank, quarantine tank — track them all from one account. Switch between tanks in one tap.
