50 lbs 50 lbs compressed CO2 52.63" 7.25"

NOTE: When measuring for height restrictions, add 1" for the regulator (meaning that, when installed, the top of the regulator is 1" higher than the top of the valve on the tank)

Only the 20lb & 50lb come with a black plastic handle.

To find a suitable place to refill, look in the yellow pages under: "welding gas supply", "beverage supply", "paintball supply" (note: "welding gas supply will usually be the cheapest) Beware of gas supply outlets that want to "lease" you a cylinder for 30-40 cents per day. Some gas supply outlets tell you they won't fill "your" tank, because they want to leverage you into buying or leasing a tank from them. Either tell them you have a "brand new" cylinder and don't want to exchange, or tell them you will simply shop elsewhere.
Why buy a new cylinder from us?
Because we have the lowest prices anywhere. And the quality is excellent, they are constructed of nice "brushed finish" aluminum alloy and have a top quality CGA320 CO2 brass valve.

    5 lbs. Co2 Tank

    Posted by Nick K. on Oct 19th 2020

    I went to Amazon to get this, first. What a disaster that was! Ordered 2 "Luxfer" tanks and neither of them were! They were both Japanese tanks that have a warning sticker on them about lead.... Geez! Who wants a lead tank?!? I talked to someone who never ID'd themselves from here and they helped me for about an hour to assure me that I would get a Luxfer. I got it in about 3 days, I live in Pennsylvania. The hydrotest date was about 2 months old, which is good. I haven't seen anything better than it in my years buying these. It was a shiny, new, Luxfer tank. Exactly what I wanted, I don't know how you can sell Co2 tanks on Amazon and claim they are Luxfers and then send a cheap, lead tank made in Japan, seems like that would be illegal in the USA, doesn't it? I would definitely buy from here again and I highly recommend getting it from here, the prices are excellent, they ended up (with shipping included) being about $2 less than Amazon. So, I was thrilled to get it and would definitely buy from here again, I just can't say enough nice things about this place!

    A good source for CO2 tanks

    Posted by MSF on Oct 5th 2012

    Received my latest CO2 tank from I ordered a 20 lbs tank this time. Upon receipt of the 20# co2 tank from UPS, I noticed that the tank was too light. The tare weight (empty weight) on my 20 lbs co2 tank is 25.4 lbs. So I weighed the tank on our calibrated scale. It weighed 28 lbs. I contacted, and spoke with Chad who was as mystified as I was. Where did all the CO2 go? According to aquariumplants, the tank left weighing 44 lbs at the time of shipment. The economics: I paid $169.99 + $6 shipping for a full co2 tank. An empty 20 lbs tank is $118.99 + $6 shipping The difference: $51 I received a near empty co2 tank, but got a partial refund for the cost of filling the tank ($27). The hazmat fees, according to chad, are figured in the cost of the "FULL" co2 tank, so I wasn't refunded the full difference. For the record, there is no leak in this CO2 tank. It's holding pressure just fine.

    I bought a 10# tank with the Ultimate CO2 system. It is so efficent that the needle has barely moved in a month. I have heavily planted 55 gal tank that is growing STRONGLY. I could have used a smaller tank easily in this application.

    Great Quality CO2 Cylinders

    Posted by Jim on Feb 12th 2012

    The three Rose Sword plants which I purchased from AP were recently removed from their pots and are now growing well, having established their roots in my aquarium's substrate. The Milwaukee MA957 regulator I purchased from this company is a bargain, given that it includes a solenoid valve and bubble counter integrated into the MA957. At first the low pressure gauge would not move, leading me to believe that it may have been defective, however, since that time the low pressure gauge now registers, so it must have been a stuck valve. This MA957 regulator combined with the Aquarium Plants CO2 tank work well together. Kudos to the people at AP, since they run a top flight operation with quality merchanise.

    Great Product

    Posted by Lenny Leung on Jun 10th 2010

    Item arrived in great condition and filled with co2. My only issue was customer service telling me when it would ship. I called 3 days in row and they kept telling me it would ship that day. They were very polite and professional.
