Calcium Reactor Media

[chessmanmark]

I recently acquired a friends old MRC calcium reactor. I need to order a new sponge for the reactor and was wondering about what brand or size of media is considered good. I was thinking of buying the Carib Sea ARM media which is sold on the MRC website as long as I was ordering a sponge. Anyone have an opinion on this?
