What would be a good deal for a used 75g with stand? I believe has filters. It's on craigslist and what is the cheapest I can get lighting for?? I'm trying to work a deal but I'm not sure... I know PetSmart has a new tank/hood combo for around 220 something but no stand and filters... I do have an old dresser I could use but then I would need to buy filtration... Any ideas??
