Cleaning a feeding station for hospital tank

[AllyssaM23]

Hi, So I got some Diamox for my seahorse. So first of all I use a Breeder Box to feed my seahorses right now, If I put the Breeder Box in the Diamox tank how do I clean it to make it safe to switch back to the Healthy seahorse Tank? I am going to use a 10 gallon for hospital tank and I've had alot of luck using this it's hard for him to see I don't want to use anything else for him.

Get a new box, mark it so you know which ones which and don’t risk infecting the DT from contamination or medication used in the qt.

Otherwise soak the box in a bleach solution for 24 hours, air dry after a fresh water rinse is the typical method folks recommend even though a 15 minute dip in bleach solution is probably more than adequate to clean up the box of plastic.
