Sponges can bind rubble piles together.  They do it quickly, and are 
aesthetically appealing and inexpensive.  Easiest to use are 
branching species because they can be simply inserted among the 
rubble pieces.  If there's enough current to move unstabilized rubble 
around, just cable tie each sponge piece to a piece of rubble before 
inserting it in the pile.  Most sponge species will firmly attach to 
multiple pieces of rubble in 1-4 days.  The branches from which you 
cut sponge pieces will regrow.  Coralline algae and bryozoans will 
recruit and bind your rubble further, as they grow from one piece to 
another; and coral larvae consider sponge-bound rubble suitable for 
settlement.  A couple of references:  Wulff, J.L. 1984.
