Thanks Steve.

The link didn't work directly but I figured it out and got it :

I got both volumes.

I have a very successful reef and sponges naturally grow on and inside the rockwork I made out of PVC and concrete. I use the hollow PVC pipe as skeleton and cover it with a fabric of concrete, then drill holes to allow water to go in and out of the hidden hollow network.

I had no plans to build habitats for sponges. I was doing it to create open structures with the least and lightest media. First pods and worms used the holes heavily, then feather dusters and sponges. I might cross-section when I take it apart.

Corals growing out of the water and little protected zones of algae no one can get to:

But overall very healthy

I don't run a skimmer but I have a large settling filter/algae scrubber and a large fresh air injector. I don't export anything- I just recycle all the algae back through my fish... settling filter just creates a worm and pod friendly habitat.
