I don't know Ace.. With GlassCages larger tanks I have heard horror stories about the lack of support, breakage and a lot of other things that really make me leery of their tanks in general. I don't know if something as small as a 57 gallon would be as bad as some of the stuff that I've heard from a couple of local reefers who have owned and ended up with 300 gallons on their floor... I have looked at the starfire glass as well and like you stated I have also read that it doesn't make a big difference in anything under 1" thick glass. But then all of this is second and third hand knowledge, none of it is first hand.
