What gallon sized tank would be 6' long, I know there must be a good many, but in general? My son's boss has a tank, that's been sitting in his garage since he got it. Not sure what it was used for before he got it, probably salt. He says it comes withe the sand in it and and it's a drilled tank, so it's got to be pretty big. He says the lights come with it and "they're good ones"(not hood). Apparently this guy has no idea about tanks, so when I get home, I'm gonna take a ride to go see it. He wants 250 for it. I'm sure I can get him lower, but how much remains to be seen. I guess it would also help to know, how bad this guy wants it out of his garage. Oh yeah it comes with a wooden cabinet. Made for it. whacha'll think? Worth a look?
