BUYING A CO2 TANK / CYLINDER
CO2 tanks (or sometimes referred to as cylinders) don't usually come with CO2 systems, and usually cannot be shipped anyway. So, we recommend that you purchase your tank from your own local supply store and save big money on shipping and on the tank! Places like: Welding Supply Stores, Soda Bottlers or Vendors, and definitely Liquor Stores who sell Keg Beer will be able to accommodate your tank needs. There are many tank sizes out there but a 5lb cylinder is the most efficient. You should be able to find a good 5 or 10 Pound cylinder for about $50 bucks or less! Re-filling a tank should only cost from $12 to $15 depending on the store and should only need to be done 2 times a year at most. Ask your supplier for a used, or rebuilt tank for an even better price? Before calling anyone, be sure and measure the maximum height your tank can be so you can hide it under your tank in the stand.
Here's some good advice on getting a tank: It is possible that your state requires you to get your cylinder re-certified every few years to make sure it's still in good, safe, working operation. Many of today's cylinders are stamped with a date on them. Re-certifying a cylinder can sometimes be a hassle and cost you a few bucks and a few hours of precious time. If you don't get it re-certified you may be turned away to get your cylinder refilled. (Propane tanks are very similar) So, here's what we suggest; get your Co2 cylinder from a liquor store that sells keg beer. If they sell keg beer, then they certainly sell the equipment to operate a Co2-ran Kegmeister or beer tap. Check your yellow pages for a store close to home. If you go into your neighborhood liquor store and ask them for a 10-pound cylinder (see what other sizes they have available) for your Kegmeister, (if you tell them it's for an aquarium they might not understand) have it filled up, they won't ask you any questions and they will take a credit card number from you for the deposit on the cylinder. Typically a deposit is a cheap as $35 to $50 bucks. In 8 or 10 months when you go into the same store to have it filled again, they'll just charge you for the refill and that's it. Here's where this is a good idea.....one day that cylinder you got from that liquor store is going to expire and need to be re-certified. Well, when that happens, the employee will recognize that it is one of their cylinders, and just swap it out for a fresh one. Done! They won't charge you for a deposit on the new one, and everything is good. By then, they'll recognize you as a regular customer anyway. Your probably gonna end up buying chips, milk or beer from their store anyway. Everyone wins!
Lastly, with paintball wars becoming so popular, folks are needing to get CO2 cylinders refilled just to shoot their guns, so sporting goods stores are just starting to carry CO2 gas. This means it is only a matter of time before big box stores like Walmart carry CO2.
