I am wanting to build or buy a bait tank. I have a 24' bayliner and would like to put a bait tank on the swim platform that runs across the back of the boat. The main thing I am trying to figure out is how to keep fresh water flowing in my tank. I know I will need a pump. I just don't want to put an inlet in the bottom of my boat. Could I put a piece of pvc down in the water? I want a system I can easily install and remove.
