Last year the c02 tank I bought from aquarium plants.com (5lb) ran out, and I've went to a hardware store and sports authority to fill it up, but they both said they can't fill it up because something about the top and how it won't fit or some jazz. Do I need some sort of adapter or is there another place I can go to fill it?!

Take it to a place that does fire extiguishers or a welding supply store.

Go to a welding supply store. They will exchange the tank for a new one. Like when you exchange a propane tank. Costs about $15

You don't necessarily get a "new" tank. You get what they have. Most likely a steel tank that could have cadmium dust on it from welding. You'll never see the tank you purchased again. The only benefit you get is that you won't have to pay for the hydro test every 5 years.

Hi s0ulcommited,

To the best of my knowledge, CO2 is CO2. I would go with the least expensive.
