Wasn't sure where the most appropriate place to post this was, but we have recently concluded a nearly yearlong study on the appropriateness of our materials for making custom artificial reefs and other decorations and have found them to be aquarium-safe. You can see one of our tanks here: http://www.ratemyfishtank.com/friendemail.php/36627

We just launched a series of tutorial videos here: http://www.smooth-on.com/Aquarium-Decor ... index.html which covers how we made our sea fan, finger coral, sea sponge, live rock, anemone, and foam backdrop.

We probably met a few of you at MACNA 2011 and wanted to get feedback from the rest of the community. Please let us know what you think about these videos, the process of making your own custom coral, or anything else we can do to improve on or support this application.

Thanks! :)
