After going through the power-outage worried to death about our pond, I
must
buy a battery operated oxygenator. All I can find is a tiny one (around
$13)
which is made for transporting your fish - don't think that would help
much.

Is their a larger battery operated oxygenator available anywhere? Any
other
"must haves" in case this happens again? Thanks for your help. Cathy
