So sorry, Maureen, about your pond problems this winter. Sometimes even Mother
Nature can't save her ponds with the kind of weather you've been having. You
really put up a fight, though!

I agree with Bonnie.
Start over, get some plants in when it warms up,
give them a head start so they can handle the fish before your filter kicks in.
Take it slow and easy. Add just a few fish at a time. Nice they are coming from
your sister's pond.
good luck!
