The Differences Between and the Debate About Glass and Acrylic Tanks

[gimhchng]

Hi guys, I just bought a 2nd hand five plan 2ft tank with black plastic rim. When I knock on it, it's really sound like plastic. Then I did some research and found this thread. Is it confirmed that five plan tanks are glass?

if you are talking about 5-plan tanks.. its glass.. i've broken one of those too.. and when it breaks and is separate from the tank.. you can definately tell it is glass. The sound you hear when it is on the tank is because of the black plastics that surround it.

you might have to break it to see?

The five plan type of small glass tanks available in the market are made of glass, not acrylic, despite the misconception.

On the Japanese label (the removable one) it clearly states グラス製, which means made of glass. The thinness and the clarity sometimes mislead hobbyist to think that it's plastic/acrylic instead.

Cheers,

Is there any other Japanese word in the label? Google it and it seem acrylic is sometime called acrylic glass.
