while I don't own this rock first hand, i have seen it before in person and while it is somewhat dense it also has some great porosity.
that pile of rocks thrown in the ocean was thrown in, if i remember reading correctly, about 17 years ago, and it wasn't just rock, it was Over one million pounds of imported Bahamian coral rock - see here - http://tampabaysaltwater.com/about/index.html
