I learned about coral culture in suspension from the article that greenspottedpuffer posted so have a look and then ask if you think I might be able to answer any additional questions. The main advantage I found was that I can cram a lot more frags into a 50gal because I can use the entire volume to place frags anywhere I want.

If I do modify my trough for frags I think I wont bother with an egg crate shelf, instead I'll pour a 1" sandbed over the bottom (to create a reflective surface) then lay LPS and softies on the bottom and continue to grow my SPS in suspension. I can continue to grow gracillaria macro algae in there because it isnt invasive like Chaeto or caulerpa. The only real modification I need to do is change the plumbing on my skimmer a bit so that I can move it to the side and out of the way so if I dont like it then reverting back will be easy. The only purchases I need to make would be for some plumbing and larger koralias. I'll also need to make a top down viewer box of out acrylic.

Between the skimmer pump and the main displays return pump I have about 2000gph in the trough already (excluding the 50gal return pump). Would three koralia 4's work well to give me the additional flow I would need?
