Seriously:

The tank is wide enough to put in a wall - to be seen from both sides.

With the peninsula design - overflow on the end - it is PERFECT for both an island AND for a 2 sided viewing tank

The lack of bracing makes lighting infinately easier - no dark spots from the brace or braces, no salt on the brace to block light and make a shadow, no low lighting that's found under a brace... For instance, with MH lighting and a single brace, you HAVE to have 4 fixtures. This will save you a complete fixture.

A tank that Mamma will feel WAY more comfortable having in her house. It's STOUT.

Having an end overflow is PERFECT. Mine is set up to return from the other end - the sheet of surface water turns over every few seconds, and O2 levels are VERY high.

A 30" deep tank gives you plenty of room at the top and middle for corals wanting a lot of light, and the bottom for those that would prefer less!
