This is a 180 gallon tank re-build. Dimensions are 5' long 30" deep 24" tall. We started tear it down in June 2012. We got the tank for a steal because the front seals were leaking. We knew it was going to be a challenge to do but decided to do it anyway. After four days of carefully cutting away the silicone we finally got the panels apart. It then took us four painful weeks of scraping and cleaning to get all the silicone off the glass. Once that was done we put it back together. That was by far the easiest part. We used way more silicone than a manufacture would have, but I wanted to make sure that it would NOT LEAK EVER!!! We filled it up with water, in my house, to make sure that it was going to hold together. That was most nerve racking. All was good. We made a stand and canopy to fit our needs and set it in the wall.
