Yeah....that xenia is a weed. I've been contemplating just strait up ripping it out. I haven't yet because I know it does a great job keeping the tank clean. Before I got the new SPS frags, the xenia colony was about three times that size. I routinely have to "trim" it back. It actually has grown onto the shell of one of my snails...pretty funny looking...but really neat at the same time.

As far as stacking the LR...I did it very carefully. I got some nice 25-30lb pieces from Wolf Reef and played around for a long time while setting up...making sure each rock fit just right. The largest pieces are on the bottom and serve as pillars. Sometimes I regret how I layed out the aquascape. The arcing structure is actually not pushed back against the back glass...but towards the center of the tank instead. My original intent for this tank was to make it a FOWLR. Building the island away from the back wall left lots of swimming room around the formation. I still like it for the most part though...and the fish seem to appreciate the space.

So much for the FOWLR idea. Once I figured out I could buy a decent set of lights at a reasonable price...I decided to go for it. And here I am now...trying not to go reef poor....lol.
