Live well tablets for ammonia build up.

I have an Engel 19 quart bait box with a Frabil aerator with a high output stone. I start the day with 50 shrimp. Without the tablets, I notice they start being sluggish after a couple hours. With the tablets, they are still kicking like new until I run out (usually in early afternoon). The same brand sells a powder for baitfish. I've kept minnows kicking like new for well 36 hours without a water change.

they do but only temporarily

this ^^^^^^

only thing that really works is to have constant exchange of water flowing through it
