Hello; Having kept fish thru the decades when power filters were not reliable for various reasons i got into the practice of running some sort of air pump powered bubblers in all my tanks. This practice has helped on numerious occasions. Some of the early HOB filters i used would lose prime if the power was off for a short time and for reasons that were unclear. The air powered hob filters, sponge filters or just bubble stones have kept tanks going during such events.
I also do not feed when away for less than a week. This also helps in the event of a power failure.
Outside of the air powered bubblers the next helpful practice has been to understock my tanks. I have not lost fish during several days of power failure and no back up generator sine going this route.
