Cracks in 55g acrylic tank

Hi, 

If anyone can offer some advice on what to do about this...

I just noticed my 55g acrylic tank has a vertical line of horizontal
micro-cracks running right down the center of the front of the tank,
like so...

They are currently around 1/4 inch wide, and look stress induced. The
front of the tank bows outward, and the tank has no signs of cracking
anywhere else. I don't think the cracks go all the way through the
acrylic, but they are worrisome.

Anyone have any advice? 

The tank is manufactured by Tru Vu, and if anyone has a website or
other contact info, that would be great.

Thanks,

Squidman
