I have a 37gal.(glass or acrylic...don't know)...I purchased from a friend...last week I had to empty the tank to change substrate...today I noticed that the front panel is bowed about 1/8" in the middle...thing is I don't know if its always been this way and just didn't notice or what...is this normal..I'm leaving tom. for vaca and don't have the time to get a new tank...would appreciate any help

It sounds like an acrylic bow-front tank to me. They are made to be bowed like that.

Acrylic and glass are pretty easy to tell apart. Acrylic is like plastic, and glass is like... glass.

well what dimentions are it? dose it have square or rounded corners? generally acrylic tanks have rounded corners. if it is glass does teh tank have any bracing? bits of glass that link the back to the front?

My old 75 acrylic bowed a lot in the middle from the water pressure. One of my glass 29's bows from water pressure. It is normal and shouldn't be a cause for alarm.

1/8" of an inch isn't much at all, most tanks will bow a small amount when filled. the center brace on my 65g stretches when I fill it, it is built to accomodate a slight bowing of the tank when full.
