New Display Tank Design

Our large display tank is being built at this time(7500gallons+)and will take awhile to be setup as the building it is going to be housed in has not yet been built, so in the meantime we are building a smaller display tank that we will have complete and ready to install in about 2 months or so.... The tank will be fiberglass with a single acrylic viewing window. Dimensions in the design stage so far are, 7'longx5'deepx5'tall, the front right corner will be built with a 2' radius curve to it so that the acrylic window will go from the far left front of the tank to the right rear side of the tank, the window will be a single curved piece of acrylic. The size was chosen because of space restrictions in our house(we have a small house from the 40's). It should be large enough to house some small schools of fish and be fairly impressive to see, the tank itself will hold about 1200gallons, with additional volume held in multiple sumps. Havent decided on skimmer yet, mabey a ETSS quad 1800, I would consider a RK2 like I will be using on its bigger brother but I am housing the filtration below the tank in a cellar with 6' ceilings so I am height restricted.... This tank will feature some nice fiberglass rockwork but I do want to incorporate liverock into this display as well to aid in bio-filtration. Was probably going to do fiberglass rockwork on the left wall as well as the back wall with an additional pillar towards the right front corner of the tank where the acrylic viewing window curves, good chance I will put an additional overflow in the pillar as well. Lighting will probably be 4x400W metal halides and a bunch of power compact attinics, unless I can sort out the LED lighting I have been working on(hopefully) I have a new line of pumps that I am carrying that I will be using, very energy efficient with good flow rates. Will use a 1hp chiller to help keep it cool, havent decided how to finish the outside yet, the tank will be insulated and mabey it will get framed with anceint roman pillars or something... th tank will sit about 1 1/2' of the floor and extend to the ceiling with the canopy fasade in place. Ill update with pics as construction commences...
