Maintenance

Maintenance holds the recurring jobs a tank needs and the reminders for them. Open it from the shortcut row at the bottom of the dashboard.

Compliance, overdue count, and each task with its last completion and next due date.

The summary

At the top:

  • Maintenance Compliance: the proportion of tasks currently done on schedule
  • Overdue count: how many tasks have passed their due date

Each task in the list is colour-coded by urgency: overdue, due soon, or scheduled. Every task shows when it was last completed and when it is next due.

Adding a task

Give it a name, an icon, and how often it needs doing in days. Cora works out when it is next due.

Typical tasks:

TaskInterval
Change filter socks3–7 days
Clean the skimmer cup7 days
Clean the glass7 days
Replace carbon or GFO30 days
Service the return pump90–180 days
Calibrate probes30–90 days

Reminders

Each task can remind you, and you control the timing:

  • How many days before it is due
  • What time of day the reminder arrives

Turn reminders off for a task you would rather just see in the list.

Marking a task done

Use the task's Done control, or swipe it. Cora records the completion time and schedules the next occurrence from that moment, so a job done three days late moves the next one out by three days rather than pretending it happened on time.

Snoozing

If you cannot do a job right now, snooze it. It stays in the list in a muted Snoozed state showing its new date, so nothing disappears; you simply are not reminded again until then.

Pausing a task

A task can be made inactive (for equipment you have taken offline, or a job that does not apply this season). It stays in the list, stops being due, and can be reactivated later.

Maintenance and the journal

Completing a task is not the same as writing a journal entry. Maintenance answers "what is due?"; the journal answers "what did I actually do, and what happened next?". If a job was unusual (the pump was full of sand, the socks were black after one day), that belongs in the journal too.
