Is tempered glass really a good idea for use in an aquarium?
I seem to remember reading that tempered glass is a no no no no no no for aquariums due to the way it fails, no cracking and eventual failure, "tick" and woosh... the contents of your aquarium is on the floor. There is no warning.
i have never built a aquarium nor do i have personal experience with tempered glass "detonation" but from what i know about tempered glass i don't think i personally could use it for an aquarium.
Actually many larger tanks (55+) have tempered glass bottoms so I would think it's fine to use for a tank.
For a tank this small I don't think it's needed at all and would be very expensive.
