This is my first tank in the last decade or so. I used to have a "reef" tank back in the mid 80's; but, was out of the hobby while pursuing school, career,etc. I'm now a small homebuilder here in Oregon and did all the work myself over the course of about 3 months. The tank was started in February 2001. Here are some tank vitals:
tank: 72W x 48D x 32H acylic
lighting: (6) 400watt 10K MH, (2) 400watt 20K MH, (6) 165watt VHO actinic
sump: 125gal with a 125 gal refugium
circulation: (5) ampmaster 3000's ( 4 of which are on closed loop)
heater: (2) 1000watts
chiller: (2) 3/4 hp
The tank is built into the wall....here's a pic of the equipment side of the wall which is located in my garage:
