I have 3 and 5 gallon Cambro food buckets with lids. Also, 5 gal pickle or other food buckets would work. Non-reactive is the key - and that usually means stainless, plastic, or glass. Haven't seen many glass buckets!!
The flat/rectangular food service totes with lids would be great, too. Used to use them at the restaurant.
