I am going to setup my high tech tank soon. It will have pressurized CO2, but I'm not sure where to get it. Does anyone in the Bham area have a source they could reveal to me.

I could always order a bottle online, but I'm not sure where to get it filled. I need to call a few places, but I thought maybe some people on here from the area might know a good place.
Thanks!
