Getting started
Do I have to test the water when I add a tank?
No. Save the tank and start recording whenever you are ready. Use Test water from Today or your tank’s detail page when you have new readings.
Why is a reading gray, yellow or red?
Indicators compare your recorded readings with the target ranges saved for that tank. Gray may mean no reading or no target is available. Review the accompanying text, target and measurement date. A color alone does not establish whether a tank is safe.
Can I enter only one water test value?
Yes. Fill in the values you actually measured and leave other fields blank. Check the units before saving, especially temperature and ammonia results.
Reminders & maintenance
Why is the next reminder visible before it is due?
Next scheduled is an upcoming plan. It becomes a due task when its scheduled time arrives. Completed maintenance is stored in your history; a future occurrence of a recurring reminder is a new scheduled task.
What if I already did the maintenance?
Record the work for the correct tank and task. Check whether it is linked to the matching reminder and confirm the next scheduled date. If you only want to move a task, use its reschedule or skip action instead of recording work you did not do.
Why did a notification not arrive?
Check TankRoutine’s notification permission in iOS Settings, the reminder’s date and time, and Focus or notification settings. Operating-system delivery can vary; open the app to review what is due.
Backups & moving devices
How do I save a backup to iCloud Drive?
Open Settings in TankRoutine and choose the backup export option. In the system file interface, select an iCloud Drive folder and save. Wait for the file to finish uploading before you rely on it from another device.
How do I restore a backup?
First export a current backup if you want to keep your existing records. Choose restore in TankRoutine’s Settings, select the backup through Files or iCloud Drive, and review the restore confirmation. Make sure the file has downloaded and is the version you want.
Is a CSV file enough to restore the app?
No. CSV exports are for spreadsheets and data review. Use a full TankRoutine backup to transfer or restore the app’s records and tank photos.
Why are my iPhone and iPad different?
They hold separate local data. Saving a backup in iCloud Drive does not continuously sync the app. Export from the device with the records you want, then manually restore that backup on the other device.
Pro & contacting support
How can I restore my Pro purchase?
Use Restore purchases in the app while signed in to the Apple Account that made the purchase. An internet connection may be required. Apple handles payments and eligible refund requests.
What should I include in a support email?
Include your device model, iOS or iPadOS version, TankRoutine version and the steps that led to the issue. A screenshot can help. Remove personal details, and do not send passwords, payment information or a full backup unless it is needed.
