OK. I already had a 20 gal, a10 gal, and a 60gal, and I had a few others that were either stolen or broke, but I have to mention a couple acquisitions that really saved me money. There was this guy who's wife made him get rid of all his stuff and I bought it all for $240!: One 100 gallon, one 40 gallon, one 55 gallon , and one 10 gallon tank as well as two really nice cabinets. I also got tones of powerheads, a magnum canister filter, a bunch of hang on filters, chemicals, test kits, heaters, lights, nets, etc etc etc! I probably saved $1,500-$2,500 with this guy. I also found some 4 ft double twin 95 watt power compact lights in the garbage of an aquarium store.(yea! I'll need new bulbs). Sweet! I love dumpster diving!
