Fished In Mobile Al for 6 years and never lost a fish, and that place was the absolute hottest place ive ever fished in July and August. I mean disgusting heat. Kept livewell on 3 min recirc and aerator on manual. Never once found a need to install some aftermarket component. I did however freeze two water bottles filled with rejuevenade, and dropped one in about 9 and then another in at noon.
