 The best idea would be to sink old ships. This makes a good platform for 
coral life. Look at most of the reefs today they have incrusted old ships.

Seems to me that if you are going to construct a coral reef away from the
natural shore line (precludes sinking old ships [a waste of steel
anyway]), you need something that

1--is inexpensive
2--will float
3--has some rigid components (dont know if coral will attach to a
flexible plastic)
4--will not float too deeply nor too shallowly (to expose the coral to
the air for too long).  
5--allows water flow around the coral to feed it
