I used to live a less then mile from Toll Gas in Plymouth. That was the first place I went for CO2, but quickly found out they were charging higher prices. Cracked open the yellow pages, called up almost everyone under welding, and Minneapolis O2 was the cheapest supplier I could fine. That was the middle of last year though and things could be different now, but giving them a call to see if they will work out for ya.
Dude! I work a block from Washington Avenue in Minneapolis! I could take a stroll on over there to get my CO2 bottles refilled!
Two 1 GA desktops, a 5 gallon, a 2.5 gallon, a 10 gallon, a 20 gallon, a 25 gallon, and two 75 gallon tanks, all planted.
I am an expert on algae, so ask me if you have questions. I know how to grow it, just not how to get rid of it.
Well, I just wanted to state that I have contacted all of the places listed and Minneapolis Oxygen was the most courtous on the phone. AND they had a great price, I went there today, the store off of lyndale and the guy who ran it was awsome, even helped me with my regulator. Gotta give them a Plug
Definitely go to Minneapolis Oxygen. They are by far the best to deal with, if you call around to some other welding supply shops you'll see what I mean. The guy at the Bloomington location ((952) 884-5286) was very nice and was used to dealing with others in the hobby. After I called he picked out and saved a brand-new shiny 20lb for me!
I know this thread is old... I only was only able to find a couple places in Rochester, MN so far.. and the cheapest I have found is the local Praxair distributor.. he said 65.00 and then 9.xx to refill and they just exchange them because they are filled in the cities. The other place here in town wanted 95 for the 5lb tank.. he said the 10lb tank is about the same price but 20.xx to fill.
