Thanx for the comments everyone.
Mrs. Kiefers I don't believe I have anything in the tank that I started with way back with the exception of the orange montipora. The tank has been through so many redos, rescapes, biotope this, try that, I have been almost continuoulsy trying new things. When I do I tend to take things back to the LFS for store credit and move on to something else. The critters I have in there now are probably the ones that I have stuck with the longest, as evidenced by the size of the coral now as I purchase only small frags when I do so I can watch them grow.
Kief the BioCube has been really fun. I have done a lot of modifications over the years and am for now happy with the setup. If I were ever to start over I would fabricate an all in one tank from a standard size aquarium, truth be told I have though about doing so with a 75 wide tank, 60" x 24" x 12" from Great Lakes Aquarium but alas I am hooked on the ease, low maintenance cost, and 5 gallon water changes the Biocube affords me.
I know what you are saying about bare bottom
but I did like this iteration of the tank.
Here is another thread on one of the reef mind melds I went through.
