I have a question, if anyone is still apart of Reef central since this post is very old! I just acquired 4 panels of tempered glass for 30$. I live on the island of Guam which has very limited tanks and they are way over priced, so DIY is my only viable option. Can I build a tank that using front/back and side panels that are tempered? The measurements are 41" x 19 1/4" and 1/2" thick. The tank would essentially only need a special ordered bottom and bracing for the euro. If i do low profile/minimalist aquascape there is no chance of a rock falling (hopefully)... will the pressure and tension be okay with this glass being used? I could even do injection method to avoid putting the pressure of the glass on each other, but more on the silicon. Also there are a few very small chips on two of the corners.
