New Reefer, What do I need to back up and how?

[cpalminteri]

I see everyone saying I should have a backup pump and heater etc. If I'm going on vacation for multiple days how can I automate it so the backup pump kicks in should the original somehow fail?

There are only two ways I can think of. Have a backup reef friend or maintenance person that can come over and switch out the pump or have dual pumps running with return lines.

I have dual heaters with controllers, spare return and ato pumps and a Wyze camera on my tank. I am considering getting an additional ato because my Tunze can stop reading the water level when it gets film on the sensor.
