OK... now that we have discussed acrylic over glass and visa-versa, shall we now discuss which salt is better? If not that, then how about whether 20K's blue looks better than 10K's less blue?
marcusbigdady: First of all, thanks for the kind words. The sand looks different per photo based on what time of day the shot was taken. Utilizing the opposing, dual and alternating closed loop systems creates alternating currents that constantly but gently move the sand about from side to side.
The lighting cycle is set automatically to our local coordinates (Central Valley of California) so the tank light coincides with our actual daylight. This is achieved via the AquaController III Pro and Aquanotes.
I do 50-gallon water changes once every month.
Chris: Thanks.
sick1166: I was lucky enough to have a brother who works at a museum that loaned it to me but your best bet would probably be to check with your local tool rental shops.
DKreefkeepers: A DIY CNC to DIY acrylic projects? Now we're talking.

Have you any links to a site with more info?
NewMariner: I give frags away regularly but do so to locals only and the occasional regional frag swap donations. But this is the case only because I don't care to deal with shipping. Sorry... unless you'd like to travel and pick them up. It would give you a chance to see the tank in person if that appeals to you.

Oh, and congrats on the potential new frag of your own.
Joseph.
