Yeh as everyone has said that will be excellent. We all know goldfish are messy little buggers and well as long as his tank is cycled his media should be packed full!
My best advice is when you get it don't just put the block of sponge in one piece in one place in the filter, Shred it up a little into wafer thin slicers and place it at high flow areas at the very first part of the filter.
That is the method I have used to cycle a few of my filters and it works remarkably fast, the idea is at the first piece of media it contacts any bacteria etc which breaks loose will then have the ability to pass onto all of the media down line, the wafer thin part is to promote an even spread of bacteria rather than having most of your bacteria concentrated in one main area.
Good Luck!
