If you mean electrolytes for live bait or livewell care, the strongest matches are Sure-Life Bait-Buddies Oxygen Tabs, T-H Marine G-Juice Freshwater Live Well Treatment, and Sure-Life Better Bait 10oz. They’re all aimed at keeping baitfish or caught fish healthier by improving water quality and adding electrolytes.
Amino+ is different: it’s a bait additive for carp bait making, dips, particles, and groundbait, and it also includes electrolytes.
