Craig, Do you weight them down with anything?
My supervisor and I installed the first round of habitat cubes in El Dorado recently. I put together a short video showing the installation of the cubes with some underwater shots of the finished product. I plan to check back on the structures regularly to see how they perform.

Blackdog40,
The lower frame of the PVC is filled with gravel/concrete to add weight. We'll see how these do. Other states have used a cinder block instead of filling the frame with weight.
