Can I "seed" jellyfish sponge & media in reef tank?

[duganderson]

I'm restarting my Jellyfishart 2 gallon tank since it's currently dry. Can I "seed" my sponge and media in my reef tank to get it cycle faster or are there creatures or things from my reef tank that may be dangerous to my jellies that my hitchhike into my jelly tank in the foam or media?

THanks, Doug
