Does anyone own or have pictures of a Lee-Mar tank with an EXTERNAL overflow? Considering the setup below but can't seem to find any pics of the overflow. Also, any input on their tanks in general would be appreciated.

36x18x18 (LxWxH) Lee Mar Glass Aquarium - 3 Sides Starphire
Rimless/Braceless
1" External Overflow
3/4 " Return
3/8" or 1/2" Glass??

Thanks!
