Myka who ever suggested making your own had a good idea, lots of people have done it, it's not difficult and to make it more porous you can add 1 part course salt. Some people suggest you add pasta (dry) but I found it was difficult to rinse off, and out. You can cure your rock in the back of a toilet for a few weeks, it works great. I found the cement at Revy for about $60 but that was enough to make a few hundred pounds of rock. Some people use oyster shell in their rock but I just stuck with the aragonite rock and it worked out well for me.

if you can tell the rock place to declare the item as a "gift" you wont get the brokerage charge with UPS IIRC. Broker is for importing
