The dimensions with stand and canopy are 8 feet long, 2 feet wide and 67 inches tall. The tank alone is 8 feet long, 2 feet wide and 27 inches tall.
It does have built-in over flow boxes shown in the picture.
There are four 2 foot long florescent light strips at the top with 50/50 actinic bulbs. I have a few extra bulbs too. These lights are new and do a great job with colorful fish including salt.
The substrate is white sand with large black pebbles.
Serious inquired only please.
