Bracing Help

[hink]

Yeah i thought so too make it nicer looking and just piece of mind really lol. I have read both sides of this but it seems the brace matters more so in the smaller 50 - 75 gallon tanks most likely due to glass thickness i could measure but seems like 5/8 thick glass. thicker than the 1/2 inch 90 I have that for sure. Is that the principle rimless tanks are built on? Mind you I seem to see those being more square than rectangular.
