Nothing slips through the cracks
Life gets busy and the test kit sits in the drawer—until an alkalinity swing or a bleached tip reminds you the hard way, and a coral pays for it. Meta Reef's free reef tank reminders flip that around: set a care schedule once and the tank tells you what it needs next—tests, water changes, dosing—on its own cadence, so a missed chore never turns into a loss.

Recurring or one-off tasks
Set up water tests, water changes, dosing, filter cleanings, and equipment checks as recurring tasks—or add a one-off reminder for a single job. Each tank keeps its own set.
Cadence + grace window
Every task has its own cadence—every 7 days, every 14 days, whatever fits—plus a grace window, so "overdue" means genuinely overdue for that tank, not a rigid global rule.
One-tap dismiss, with undo
Snooze or skip a single occurrence of a reminder with one tap. Changed your mind? Undo brings it back—a dismissed reminder returns and a woken task picks up right where it was.
Pause, resume, edit, delete
Going on vacation or breaking down a tank? Pause any task and resume it later. Edit a cadence or delete a task entirely whenever your routine changes.
How reminders work
Reminders are derived from your tasks and your logging history—so they stay honest to how each tank actually runs. Three steps, and your reef tells you what it needs next.
Set a cadence
Tell a task how often it should happen—test alkalinity every 7 days, change water every 14, dose daily—and give it a grace window that suits how forgiving that job is.
Get reminded in the window
As each due date approaches, the reminder surfaces on your dashboard. Within the grace window it reads as due; past it, genuinely overdue for that tank—no false alarms.
Dismiss one or complete it
Skip a single occurrence with one tap, or log the task done. Completing it advances the next-due date automatically. Undo is always there if you tapped too fast.
Completing a task from your maintenance log advances its next-due date automatically—no due date to reset by hand.
Why a reef needs a schedule, not a memory
A reef is a slow system where the cost of a missed water change or a skipped dose shows up weeks later, in an alkalinity swing or a coral that stops growing. The habit that keeps tanks healthy is consistency—and consistency is hard to hold in your head across a display tank, a frag tank, and a quarantine that each run on different rhythms.
Meta Reef takes that off your memory. Each tank carries its own tasks with their own cadences and grace windows, so a reminder means something specific to that tank instead of a one-size rule. Because reminders are derived from your tasks and your logging history, logging a job done is all it takes—the next-due date moves forward on its own. And when life gets in the way, you can dismiss a single occurrence, pause a task entirely, or bring any of it back with undo.
Keep more than one tank? A cross-tank schedule rolls everything up, so you get one schedule across all your tanks and can see what is due today in a single glance—no whiteboard on the stand, no scattered phone alarms.

Reminders & schedule FAQ
How do I remember to do reef tank maintenance?
The reliable way is to let something else keep track for you. Meta Reef turns each recurring reef chore—water tests, water changes, dosing, filter cleanings, equipment checks—into a per-tank reminder with its own cadence. As each one comes due it surfaces on your dashboard, so instead of trying to remember when you last tested alkalinity, you just glance at what your reef needs next. It is free and works on any device.
Can I set recurring reminders for water changes and dosing?
Yes. Any task can be recurring on the cadence you choose—every 7 days, every 14 days, daily, or whatever fits that job—and each task has its own grace window so an "overdue" flag actually means overdue for that tank. You can also add one-off reminders for a single task that does not repeat.
What if I want to skip one reminder?
You can dismiss a single occurrence of a reminder with one tap—snooze or skip just that instance without touching the recurring schedule. If you tap too fast, undo brings it right back: a reminder you dismissed returns, and a task you woke picks up where it left off.
Can I pause a reminder?
Yes. You can pause any task and resume it later—handy for a vacation, a tank you are breaking down, or a routine that is temporarily on hold. Paused tasks stop generating reminders until you turn them back on, and you can edit a cadence or delete a task at any time.
Do reminders work across multiple tanks?
They do. Reminders are per-tank, so each tank keeps its own cadences and grace windows, and a cross-tank schedule rolls everything up into one view—so you get one schedule across all your tanks and can see everything due today in one place, whether it is one display tank or a full rack.
Is the reminder app free?
Yes—reminders and the full care schedule are 100% free, with no hardware to buy. Create an account, add a tank, and set up your first recurring task in a couple of minutes on any phone, tablet, or computer.
