But, what if something goes wrong? I have a beautifuly planted 55g tank that had, I emphasize had, a great little population of micro and dwarf rasboras. It was filtered by a HOT magnum. Thursday night we had some storms go through and lost power for about an hour. The HOT magnum decided not to fire back up. Today, I found most of my cool little fish floating with a few staglers gasping for their final breaths. I may save 4 out of about 12 of the fish.
A small air pump with an airstone and a timer could have prevented this tradjedy. It also would have been much cheaper than replacing the fish.
A UPS is your best insurance against this happening again......DC
