That's a great idea- I was thinking of the same thing as a backup in case a pump failed or something; but never thought of a backup battery... He will have some high rez temps too so I think it's for the best that he has as much air as possible going off in it. He does have the airpumps and lines already, we just didn't install them because we thought the waterfalls would be more than enough. But you bring up a great point, so I think we need to use them and not let them collect dust.
The UPS idea is awesome- thank you very much for that!
