Hey everyone I am purchasing a new 120 g 4x2x2 this coming weekend. I have three choices as far as tank brand at my LFS. Aqueon , Deep Blue & Marine Land. Both the aqueon and deep blue tanks have 2 overflows on the back glass , the Marineland has one corner over flow. Right now i am leaning towards the Marineland since the corner over flow really saves floor space. Is one overflow sufficient ? I also wanted to know out of the three manufacturers who has the better build quality. Any help would be greatly appreciated.
