Hello all. I will be constructing a bait tank over the winter. Curious to know what has worked for you. I usually buy suckers and they are charging me $3.50 each for the XL suckers which I use for Flatheads. I need to keep them alive. I have a Engel 19 quart bait cooler that does work great for a period of 3 to 4 days. However, I need something larger that can keep these fish alive and healthy at home. What you suggest? I am thinking of using something like this guy has on Youtube https://www.youtube.com/watch?v=SDpLkYRzlQY&t=1150s i am interested in buying a different type of filter system that is more simplified than this 5 gallon bucket thing he uses. I may end up using the bucket method however.
