Angels plus has a good reputation. In theory, if they take a used sponge filter out of one of their tanks and send it to you, than yes it will allow you to place the cycled filter into your tank and you'll be cycled (in essence you dont cycle an aquarium so much as cycle a filter.....but thats semantics I suppose). However, the same danger applies as with bottled bacteria. Bacteria is living and needs to stay living from when it leaves their tank and gets to yours. That means it has to stay wet, cant see extreme temps (which shipping can sometimes see crazy swings like in a plane), and cant go too long without an ammonia source.
