Receantly when I put catfish in my livewell they die pretty quick. By choice I CPR most of my fish. This may be stupid to ask but do you have to clean your livewell with soap our bleach ever once in a while to keep them clean? I always leave it running so there is plenty of fresh water in there at all times. This use to be no problem at all they would survive all day summer or fall. Thanks for any help.
