ok guys, i could really use some help here. i have tried multiple things over the years and i cant seem to figure it out. after this last trip im done and looking for help. i cant seem to keep bait alive longer than a day. and that is really pushing it. my boat uses a thru hull pickup and the tank is on the back. i get a 20 dollar scoop from nacho and they start floating within a few hours and just keep dying from there. i know its not his bait because the exact same thing happens in San Diego. so here is what i am CURRENTLY running and what i have done in the past. currently i have a 1000gph tsunami aerator pump on the thru hull, 1 1/8 line running to the transom fitting, then 2 hoses going to the tank. i used to have both hoses hooked to my spray bar in the tank and i found the bottom area of the bait tank was a death trap. i have since used one hose to the drain instead and that seems to have helped out some but they still are dying. I started with 600 gph and that couldnt keep up with the tank. switched to 800gph and that was better but still dying. 1000gph seems to last the longest so far. i have put in a bubble maker to try and help and that did more damage than good. maybe too much air? i really envy you guys that can go to catalina and keep bait alive for a weekend. maybe a bigger tank is needed? really hoping to figure this out soon.
