what size is your CO2 tank

[The Reefer91]

i'm just curious as to what size CO2 tanks you guys use for your calcium reactors. i was considering either a 1.25lb(20oz) or a 2lb when i do a clacium reactor on my 50g.

what size do you guys use?

[JetCat USA]

10 lb

[The Reefer91]

jysus, that's a large tank!

[Orochimaru]

10lb for me and I also got a 20 for back up.

how long does your 10lb last before it needs refilling?

[JetCat USA]

10 lbs lasts about 10 months, if the 100 lb bottle off my MIG welder would fit in the stand.............

what kind of demand do you have out of your tank? some people a 5 lb bottle lasts a few yrs, others a few weeks.

I have a 10lb because I got it free from a friend. It's hidden in the closet.

[bonbon2007]

1.5kg and I'm useing it together with Schuran pico.

[LobsterOfJustice]

5lb, lasted 1.5 years on my 75 full of growing-out frags.

Since I have a large tank, and I hate to go have the CO2 refilled too often. I have a 20 lb.

I have a 20lb the 5 lb just lasted about 5-6 months with my Schuran Jet Stream one.

[AZDesertRat]

5 lb and it lasts 6 or 7 months. The 10 lb bottle is for my beer kegerator!

[RobbyG]

10lb. Still going strong after 8 months.

5lb. just got it today $78.00 from reef geek. Not meaning to hijack but how many use welding supply co2 or food grade co2?

[Fishbulb2]

i use 20 lbs. It lasts me a few years between refills.

[AZDesertRat]

I get mine refilled at a homebrewing shop so its food grade!

I use a 10 lbs bottle because thats the smallest they have at the gas supplier. I don't have my own bottle. At the gas supplier I just drop off the empty, pay inside, and then grab one of the full ones on the way out. Is that unusual?

[theatrus]

20lb, as thats what PraxAir seems to always have in stock. Even local gas shops don't keep much around < 10lbs.

that's how i do my MIG bottle but i own my bottle for the reactor and it's aluminum and in mint condition, not gonna swap that out for a rusted, paint flaking off steal bottle

[AMGSiR]

10 LBS...

But it's on my freshwater tank :P

I have a 10lb and a 5lb. I use the 5lb as a temp until my
10lb gets refilled since it takes a week for the supplier to
refill a tank.

I used to use a 5 pound one on my 90. I'm not using a reactor anymore (tired of the low pH, and I don't have super CA demanding stuff anymore) so now it just sits in the closet empty.
