The fans in the hood have been replaced, with ones that are more powerful (though just as noisy):
   The fans I chose are a bit thicker then the original fans. The screw holes line up perfectly, but the original screws are too short for the mounts towards the front of the hood. The fans (in the third photo) are being run by Modular LED's fan power supply and adapter. They worked perfectly, and there was no indication of overheating. I let them run for 12 hours. This is going to be a HUGE improvement over the original components, as the fans can be left running when the lights are off. What I consider a major design flaw with the Nano Cubes is that the fans shut off when the CF bulbs shut off. It is true that the fans will be underneath the splash guard (when I finally have the hood all put back together), and they don't do much for air exchange. But, with these closed systems, and the challenges in maintaining pH, I do feel the fans should run 24/7: no potential source of O2 should be left off. The fans came from Memory Express. Unfortunatly, Modular LED doesn't offer a 60mm fan.

 I'll be running this system at 79F.I'm very glad that you chimed in about the temperature issue, as that was something I was totally unaware of. I did know that they require a VDSB, as they build their borrows four inches deep in the wild. Now I really don't want a VDSB . . . The only consolation in it for me was the potential to house a blue spot jawfish. If I have a hard time filling the void, I may slip in some pieces of dense base rock underneath the dry rock. I have given myself a half gallon of wiggle room, but I don't want to use any of that.

 After asking around about what on earth could of caused it, I found out about their issues with higher temps. Totally made sense to me as when I 1st got my BSJ it was early spring and was cool outside and my tank sat around 76. Unfortunately as summer hit and the house heated up so did my tank but it was sitting around 79-80 so I didn't think to much of it. Until I noticed my BSJ going downhill fast and found out they do better in colder tanks, sadly by then it was to late to reverse the effects Now I try to let others know so they don't have to go through what I did.

It's a shaved down pill bottle cap with a hole in it . . .
 An itty bitty switch . . .  And a bit of #24 wire . . .  This may be the part of the build that I think is the most clever. No. I'm not telling you what it is, yet.

I just made the cutouts in the hood a bit bigger: in the event more equipment is squeezed in, and for the airline for the skimmer to poke out.
With the pH issues in these little tanks, I decided it was definately worth running the airline for the skimmer outside the tank. This could be risky, but as long as the airline stays above the waterline it shouldn't siphon any water out. I'll zip tie the airline to the power cord for the skimmer, so it doesn't fall.
