I plan on trolling and live bait fishing in it so I will be soon making a live bait cooler livewell. I plan on making it out of a 48qt cooler so any ideas would be appreciated. I want it to recirculate its on water because it gets very hot here in the south lol.
A five gallon bucket with an aerator goes a long way. I fish offshore $99.9% of the time here in South Fla. I always bring pilchard or goggle eye. Sometimes both. Lately, I've been using two aerators just because I had a spare. Last week, I had 5 goggle eye in my bucket for 4-5 hours with no problem at all. Nothing was eating them that day so I ended up releasing the leftovers. No scooping water, changing water, etc... just the aerator. I've been doing that for 3 years with no problems. Just get the water resistant ones. They last longer.
Also, a rectangular cooler could be an issue because they will swim into the corners and wear themselves out. Circular containers are better.
