Where to buy CO2 tank?

20 lbs bottles are huge too. I got one a while back and it won't fit under my tank... I am selling it to my bro-in-law as welding equipment.

I do have room next to my tank for a 20 lbs tank
New 10 lbs for $85 vs. Used, refurbished & tested 20 lbs for $55 ???
That tis the question

Why would you need to go with Aluminum?

[RobertG]

I went aluminum b/c it was outside the stand. They are ugly anyway, do you really need 20lbs. Your NuttZ! JMO! Sure would hate to see your ph drop into the 5 real quick, just guessing at 5 but if it leaks you are in for it. Poor 215G reef tank! Of course this would be the worst of luck! Have heard of it though. :( :-D

good point...so a brand new 10 pounder it is

Get the biggest tank you could fit under your tank. The bigger the bottle, the less you'll have to drive with it in your vehicle to refill it. If you can afford it, buy another bottle and use it as back up when your other tank run out. For my 55 gallons planted tank, I have a 20 pounds bottle and a 3.5 pounds as a back up. Leave the bottle under your tank especially if you have kids. Get them new and find a refill place in town that would be willing to fill it your you on the spot. The beer supply shop next to AquaTek will refill your you. They don't fill with as much high pressure, but they also charge less. Get aluminum b/c they look shiny and pretty; and are less prone to rust. Those old metal bottle might have lubricant inside to prevent rusting, you don't want that to end up inside your tank.

ok i just called welder's supply
Aluminum 5lb = $85
Aluminum 10lb = $122

So an extra 37 bucks for twice the size.

Fill that new 10 pounds aluminum up, and I'll trade you my used & filled 20 pounds aluminum. Let me know if you need a picture of it. I live on the third floor and are looking at reducing the weight load.

[RobertG]

Sounds good there. 122$ buck for a 10 lb aluminum cant beat that. Sure will be pretty looking! 20 just way to much!

Good Luck, keep that bottle upright! Drive Carefully! :-D

I got my tank from the beer place next to Aquatek too. I got it for $75.00 (5lbs). They only put about 2lbs in it for $5. I've been taking to Airgass on Lamar, they fill while I wait and they pack it to 5+lbs for $7. It forms ice on it when they do it.

Extra cost is not a factor anymore when you figure out it's cheaper per pound to fill a bigger bottle vs. a smaller one.

So an extra 37 bucks for twice the size.
