Starphire, 30" tank

[Majestic_Aquariums]

I will be ordering a 30" tank in August, but am now faced with the fact starphire glass only comes as 1/2". The tank size is 84" X 30" X 30" and am told it has to be 5/8". The only question I would have is would full eurobracing allow the tank to be made of 1/2"

I didn't bother getting eurobracing quoted, as the glass in the miiddle isn't a huge concern. The rockwork (and eventually corals) will be on either side of the top glass.

I checked into an acrylic, Tenecor wants 4K for a tank that size, and there aren't any wholesalers around. Besides, I don't know how much open space on the top a tank like that in acrylic would have either-and scratches easy (er)

The 30" tank I already have is reg. glass and doesn't look too bad w/MH on it. Is the difference to starphire worth it anyway?

If anyone has any input, that would be great, I don't want to regret a purchase like this later, thinking "I wish..."

Thanks
