Nice start! I'm in the early stages of planning a 24" cube myself - I live only 2 hours drive from Glass Cages factory! Did you get the Sapphire front panel only or three sides? How big of a difference do you see with the Sapphire? Is the 'transition' to normal glass on the back noticeable? What do you think of GC's silicone work and general workmanship?
I would have gone with more flow and less light (in fact, I will be).
Is that 396gph with or without media? (This can be a big difference).
That's a honkin' big light! I've got a 150w pendant that I'll use and think I'll be fine. Good luck!
thanks for the comments everyone I have done some serious thinking and I found a local tank builder to make me a 24" cube instead of glasscages this guys a real pro he showed me some of his tanks and the trim and edge work and it is flawless. he has a way of bonding the tanks glass panels to make them look like there is no silicone at all.
I also decided to go extra fancy and use starphire glass panels on all 3 sides except for the back panel
I will be paying significantly more for a 24" cube from this guy than from glasscages ($800 rather than $300 from GC) but i think the end product will be well worth it. I also have decided to ditch the cannister filter and install an ocean clear module filter hooked up to a 1/8 horsepower pump giving my tank about 13 turnovers per hour, significantly more than my original plan.
I asked the guy i found to drill a hole in the bottom of the tank which serve and the ocean clears intake however the output will still be going over the edge via glass lilly pipe (im still concerned however if that fragile glass pipe can handle that much flow)
as far as the light is concerned i don't even plan to use the CFLs that come with the light all i really want to use is the 250w HQI but i couldn't find one that cheap that is HQI alone. so now after.
after my revisions it looks like my initial cost of setup (tank, light, stand, co2, filter, pump, plumbing etc) is now about $1300
funny how my vision of the "perfect" setup is also the perfect money trap
