I finally got the tank filled this weekend and got the wave2k running. I ordered the spacers to push the units a little further down the tank in order for the wave to sweep the bottom. Just added the 30gal refugium that I bought from alamo. The three blue acrylic sides confine the light to that area only. I am still finishing the sump so the tank is not quite up and running but I plan on doing this today. I have taken video of the wave 2k in operation (avi format) but I dont know how to post it. Anyway, I will continue to post updates. I will introduce some of my old live rock (rubble) to cycle the tank. The 1/4 inch HDPE for the BB is awesome.
