Are you still looking to buy tanks, etc. I have a great 135 gal DAS syatem that had an internal overflow with filtreation but removed it and added drilled overflow holes to tank. Internal is still available to put back in. Tank developed a very small slow leak out of a corner joint. I have removed all rubber corner seal but ran out of time - now traveling too much with job. Tank needs recaulking with rubber caulk. Stand and modified hood also with tank.
Also have a 55 gal with stand.
Also about 50 lbs of rock that has been allowed to dry out so it needs recuring to become live rock.
Also have a lot of light parts, starters, etc.
