i had some questions for you guys.. i am going to setup a small live well/ bait well in my jon boat. it has an existing gravity fed live well that i want to convert into one one i with pumps etc. I'm pretty clear on what i need as far as the pump to bring what into the tank etc. But what do i use to pump the water back out? Just a submersible bilge pump? I've looked around the net and haven't seen anything that seams like it is specifically for this purpose. thanks in advance for your help.
