do any one have a backup battey opp. pump i can use ?

Would like to borrow a back up my data back up just went out surge light is on call manufacter an they said resistors are blown?

Thanks to the jar head syndrome I saved my fish all three tanks with no losses my trusty manual foot pump for the bikes an etc I pumped air for 22 hrs I rigged a conector for all air lines an pumped for ten mins rest for 15 it worked. Prayers an hard work paid of doing 50 w/c on all tanks a little bacteria supplement an I'm up an running ordered a generator from harbor freight just for this reason. Well two 5 to you mud ducks I'm 10-7
