I use Bait Saver, its the blue stuff they put in the water at the bait shop. Anything to take the bad stuff out of the water, can use the stuff at walmart for fish tanks. In your case take a clean 5 gallon bucket, put the treatment in and fill the bucket. Let it sit and an hour or so and move the bait to the bucket. Pour the water out of the Engel, rinse and then pour the fresh water and minners back in the Engel.
