I am a college student and still going to school, kinda in debt but i really love salt water tank. SO i just want to get one this year. I was working if i anyone can sell it for 100 to 150? if yall can, PM thanks
Check out the local fish shops, many of them have used tanks. Your profile doesn't specify a location but I picked up my 24g JBJ at Aquatic Design for $100. I think Neptunes Cove has a bunch of used tanks as well.
check the sell/trade forums here as well. Many people will give you a good deal on a tank and I'm betting you can find something used for well within your price range.
