Co2 DIY vs Pressurized

I keep seeing posts that DIY Sugar/Yeast CO2 is for smaller tanks.

Why? If I can build a DIY system that supports 20gal, why not just triple it's size for 60g?

I haven't found a reliable place to get CO2 refills in the town I live in. Which means a 90 mile round trip to San Diego, and only able to refill on the weekends (can't get down there mid week due to work schedule).

What I was thinking was to build out a system that hooked up 3, 4, or 5 2 liter bottles as needed. each with their own bubble counter. Add in check valves so any can be detached and refilled as needed without blowing pressure on the whole system.

How much harder is mixing up a batch of sugar/yeast in 5 cup compared to 1 cup?

Thanks,
Steve

You're absolutely right! and this guy has done so!

ultimate DIY CO2 with benefits… wine byproduct!


You just gotta keep fiddling with it every 5 days.


It's unfortunate that you can't find a refill but pressurized just gives you the ability to not worry about it for months along with amazing stability if you've built your system right.

Google search shows me Airgas in Temecula, CA.
I know there are welders in your area. Is it possible you may have overlooked some of the suppliers?

Pressure CO2 IS a bite to set up but once set. It really is the best way to go for most folks.

Very likely. Never thought about Airgas. Just didn't think they serviced anything this small.

Fish store today suggested home brewer supply houses. I could have slapped my self. I home brew, but I bottle so my CO2 is from fermentation. I don't do kegs so I didn't think about that for CO2 supply.

Thanks,
Steve

Correct me if I'm wrong but some paintball suppliers can probably do refills as well.

When you mention this small, I may be thinking different about size! What size did you have in mind? I find it fits me better to use a 20 pound bottle which lasts me far longer so that it reduces taking it off as well as the trip to exchange. I find putting it together and letting set for a long time works better than me hauling it in and out so that I may break something. The price for exchange of 5, 10 and 20 pounds is nearly the same for all.

fire extinguisher service is where I go to get my 10lb tank fill with co2 ,as I wait for it only takes 5-10mins and coast around $17.99 for my own tank . I also had them reinspect a old tank that coast $35. they have to do a pressure test the tank and re stamp the date on the tank. Other places like wielding shops will want you to trade your tank for on that's full of there .

Don't forget the home brewer's suppliers. I get my tank filled at the one down the road from me. And a nice bonus is that they're open on the weekends.

Sports Authority also typically does CO2 refills (or at least all the ones around here do), and their store locators says there's one in Temecula.

I had difficulties too in my rural area. Until the idea popped in my head to check the local auto parts store.

Sure enough, they get welding gasses and were able to get me 5lb tanks delivered twice weekly at $14 per swap.

Instead of driving two to three hours round trip, I can swap a tank on my way home in the evening. Yay!

I 2nd going pressurized CO2 for the simple fact that its a steady source of C)2 rather then hoping you get a mix right. I have done DIY, Paintball, And now 5lb tank. I can say hands down I wish I had skip the other 2 and went straight for the full setup. I fill my tank once per YEAR and it's set on timer so I have to do 0 maintenance on it. Total setup cost me around $140 and worth every penny.

I know I hated having to sit and mix the DIY stuff every week.

Man Airgas is everywhere then. That is who I use. I bought a 5lb about 5 years ago but I wish I had gone with a 10lb or 20lb. The longevity of the co2 has many factors. To say it last for x amount of time varies widely. For some a 5lb can last 2-3 months. For others 1-1.5 months. It really just depends on your setup and how efficiently it is setup.

Yea, pressurized is easier. I pretty much never touch my tank other than water changes and routine maintenance. Yes, a bit of bba here and there but nothing unmanageable. Really love the fact that good quality regulators and needle valves keep the CO2 consistent.

I think we made all start out maybe being a bit blind on the ways CO2 is used. That leads us to miss some of the obvious sources that may work much better for us in our little spot on the map. There are folks doing planted tanks all around and we think about them but then there are SO, SO, many other ways CO2 is used. Bet there are home brew folks in most areas. If not, there's welding , greenhouses, paintball, and most any place has some little joint that sells soda!
