I've always been intrigued by the shallow reef setups. I love the look of the open top and the more square shape, plus the amount of space in the stand gives you endless oportunities. Does anyone know of any sites where they sell these or have DIY designs? I see some made of Acrylic and some made of glass. Also, where can you find the notched out material to make an internal overflow. I'm pretty handy, but routing out acrylic notches perfectly seems like it would be a pain in the ***. I appreciate any info you guys can provide
