Tournament Ice and minner ice. It works better to me than the release me or the bait alive stuff. I put one bottle in my left over minners Sunday morning and haven't lost a minner yet and haven't changed water either. We also use it in our club tourneys and haven't lost a fish. The first tourney we had 20 in the livewell and all 20 were very much alive at the weigh in.
