It's brand new. It's rated for 50 gallons. I'll throw in a 100watt heater and a thermometer with suction cup (both of which have never been used) for $30 + shipping. I had a project for my 20 gallon but I need the money so I'm letting this stuff go. There is also a water test kit that I'm selling too for $20 + shipping. Or all of it for $45 + shippinh. I'll have pictures by tonight hopefully.
