i keep air pumps and foam filters on all of my tanks.. that way if the power goes out all the battery backup has to run is the air pumps and my already seasoned foam filters are there to keep my fish safe until the power comes back on.
Yes and no. My feeder tank has a constantly runnin pump with bubble wall, And my 29 has A pump and bubble wall, but its only on rite before, during and after water changes.
I've always ran air on all my tanks I guess I really didn't know it was an option. My silver doesn't seem to like it so I keep it to the end that he never goes to. I guess that's why he doesn't like it.
