cutting down a tank question

I have a non-tempered 55 gallon tank and was just thinking about trying to cut it down to 14" high without disassembling it. Score the glass (inside and out) all the way around> heat score line with low flame> hit with ice cold wet sponge along score line> sand top edge and replace the top trim. Has anyone ever tried to cut down a tank in this way before?

Do not try to score both sides. You only need to score one. Kind of risky doing it without disassembling the tank first.

It's a spare tank I drilled to convert to a reef tank. Currently looking for a drilled 75 in my area instead. If I can find a drilled or non-tempered 75, I'll try cutting it down, it would make a good sump.

I would just score and pop like cutting regular glass. Make sure you cut the silicone from the corners and in between the panels of glass before you pop it.

I'm glad you suggested that, I was thinking I should wait until after popping it. That way I wouldn't ruin the structural seal of the silicone.
