I use gen-x calcium reactor media.
Here's a link to what I feel is a good price on some kalk.

I just bought a Geo reator and are using the ARM large size media. Sorry I dont have a long term experience to share.

I'm using ARM for a 612 right now, no problems with it turning to mush or anything. Works fine. I just added a CA dispenser for the osmolator to offset the low pH though.
