Picked one up for free from helping a friend move. She didn't need it, and it needs some attention. I don't know how it works, but the air pump on the tank doesn't seem to wanna pump air into said tank. How can I remedy this? What else do I need to know about this cool little guy? I remember seeing comments about them on a certain thread but I can't remember where I saw that... Anyways. Here's to new toys/survival equipment.
