As a follow-up, I spoke with Innovative Marine about the issue. Their service was less than stellar, and they offered me a IM Fusion 10 as a replacement, probably because they don't want further issues with the curved Nuvo 8 or 16. They said they don't have Fusion 10's in stock however, and they would not be able to get me one "for at least a month"! So after purchasing an aquarium that doesn't hold water, they were willing to replace it, but not for another month, which certainly wasn't an option. I ended up purchasing the CadLights Mini 8g with the optional LED, which will go well with my CadLights Artisan II 50g.
