I have a 88 181pro. I have cleaned out the livewell and made sure the fill pump worked and also the recirculator was working and fished a tournament here in Florida. we put 5 small fish in the well. The water temp was 85. I put rejuvinate in about 4 times in 6 hours and I closed the livewell drain and made sure the pumps kept running but all the fish died. any suggestions on what might have happened? I am afraid to fish another tournament because I dont want to kill any fish.
