sounds like overkill to me, but if you've got the energy for all that it cant hurt. Depending on what fish you have, if the fish aren't going to be in the 5gal. bucket for more than a day I would say you're fine. And 5-7gallons of water from your original set up should be adequate. Depending on design: I've had coolers that were pretty water tight, but that means oxygen tight as well. And I've had coolers that weren't designed to hold water at all. Clay A.

Maybe this is overkill. _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
