Hey folks,

After some discussion in chat about it, and meeting up with a paintball wizard... I can say for sure - using paintball CO2 bottles for planted aquaria is definitely on the horizon.

I say this because I found a source, and some rough pricing on some custom work...

Problem as with all manufacturers - is to make it worth their time and effort - they want a substantial minimum order (this case - 150).

How many of you out there would be interested? For rough estimate of 40us$ you'd get a fixed regulator, very fine adjustment needle valve (According to the manufacturer, they will do as low as 1bpm), and a tank side pressure guage. Just the basics - I'm sure one can add solenoids etc later if they wished.

Advantages: Basically initial price. Pressurized system for 70$us (20/24 oz paintball tanks/bottles are under 30$) Refills might be a little easier to find for those in areas away from industrial sources. Size could make them an attractive option for those with nano tanks at the office... And there is the bling factor - after all, no exchanges - so blow all the $ you want on a fancy bottle :)

Disadvantages: Long term cost - refills for the little bottles run 5-10$, and they wont last near as long as the 5lb you could get refilled for about the same price... Otherwise, it's basically the same system.

So, what sayeth APC?

I think it goes without saying that I am interested, since I was the newbie in the chat asking all the silly questions that got this started ;)

The main reason I am interested is that I have 3 tanks in 3 different rooms of my apartment. While it would be more economical to consolodate and bring all the tanks together, space requirements don't make that possible. I suppose it could be possible to have a 5lb tank in each room. However, some of the tanks, like the 10 gallon on my dresser, do not have much space around them or below them to house such a tank. With a 20oz paintball tank, I should be able to just set it on the dresser next to the tank - no problem.

What kind of custom work does this entail, Andy?

Edit: Incidentally, I managed to find the disposable CO2 line put out by ADA in Japan. LINK Those bottles seem about as small as paintball tanks. Funny part is that the gas is scented to smell like different natural locations such as "Amazonian", "Malayan" and "African"

LOL Yeah I knew you'd be in a hurry to find out :)

The custom work is basically the regulator, while I did find a 30psi regulator last night that was designed for the paintball world, after talking to the gunsmith (or markersmith or whatever you'd call him) found it would be completely unsuitable for this application. So the regulators (the one thing that is hard to find) would have to be custom made with internals designed to put out a slower steady stream of gas. To that, I also requested the 1" guage. Buying the needle valves from the same manufacturer - saves us money - <10$ each vs buying online at 25+. A few pennies (almost litteraly) for assembly saves us on teflon tape and headaches due to leaks...

One of the nice things about the paintball system, is on multiple tanks... If you have an existing tank you could use it to refill the smaller paintball bottles. A refill kit costs 40-100$ depending on quality/source, digital scale chances are you have, or can buy for a few more dollars. Then use the large tank (upside down - so it dispenses liquid co2) to refill the smaller bottles. Thus you're getting your CO2 for the same price, but can use it on multiple systems.

I'm interested! Just have a few questions.

How large is the tank?
As a double check, that is 1 b/minute, NOT 1 b/second right?
Will any welding shop have a problem refilling it?

Yes that is 1 bubble per minute, I asked 4 times to make sure...

Tanks can be found at almost any sporting goods stores, paintball outfitters or on ebay, even walmart sells them. They range in sizes from 8 - 24oz, overall size, is pretty small check out some of the paintball vendors online to see the overall sizes.

Refills - probably not by your local welding shop - instead you'd have to go to a sporting goods store that dealt with paintball gear (Someone said target refilled them? I know my local canadian tire does) paintball shop, or paintball field. Chances are you have many more local options to have these refilled than their larger bretheren. I've heard prices ranging from 1$ to 10$ (10 being my local canadian tire store) for the 24oz refill...

I'm still interested too. About when will these regulators be avaliable? Just as a side question, aproximately how long will a 20oz last on a 20 gallon? Looking at fill ups every month?

Well, I ordered a prototype for testing, should have it in 5 weeks... Figure on at least a couple months of testing - then some time for production units. Until I get the prototype - no idea on how long the tanks would last. I did find a spiffy 35oz paintball tank however - there may be even larger ones.

I actually may not be the one selling these, got an offer from a retailer - which I'm seriously considering accepting

I have been looking to do this for some time now, my only problem is that I've asked around and those who refill my CO2 tanks won't touch these cyclinders and the ones who do work with paintball cylinders use a mixture of oil/CO2 which helps lubricate the gun, none of them could garantee me that no oil would get into the cylinder so I'd have to refill these myself.

At this stage I just need an adapter for the paintball cylinder to turn into a regular pipe thread so I can use normal regulators and refill them myself. Short of making one myself I'm haven't been very successful in tracking one down.

Gpodio: your information is wrong. The paintballers use the exact same CO2 we'd get for our tanks... From the same place, with the same exchange cylinders. There is no "Paintball" grade of CO2 - just industrial and medical grades. There is no oil added (this myth comes from the days of the daisie air rifles - I've heard the little daisie cartridges had oil in them)

No updates, still waiting patiently on the regulators...

Then I need to visit a different sporting good store because that's what they told me, they said they use a little oil in all their refills and so can't gurantee that my refill would not be contaminated. Anyway, that was a regular employee, who knows perhaps he doesn't have a clue what he's talking about.... I hope so. I'll look around for another store tha does paintball refills and will let you know.

Thanks

Sorry, I must have missed this thread.

Wouldn't it be cheaper and safer to purchase the ADA regulators?

I used this system exclusively for many years. I can tell you I would get about 2 months out of the tiny cylinders.

Any updates on this? I'm interested in getting one.

Also I'd like to get a confirmation if ADA regulators will fit paintball tanks.

Ive been researching this for a bit now and found out that only certain places can fill paintball tanks.

I found this online, basically you can use a 10-20# co2 tank and fill your own paintball tanks.

I noticed that the other day but htere is no description. I don't know much about paintball but that is a drop forward I believe. Another option is to use a on/off. Depending on the type and brand, these parts thread onto the cylinder but have an outlet on the side thread for 5/32 NPT or something. Actually I believe it is the same thread the Clippard metering valves we like so much use. I read an article where you can use the on/off and the metering valve without the regulator just fine. I will be danged if I can find that article again though, had pictures and everything.

Also, most high end, dedicated paint ball stores can switch the stem on the cylinder with one threaded like the bigger cylinders. Then you can just attach a regulator right to it. That swap will cost ~30$ US. The guy at the marker store also told me you should be able to find a regulator capable of handling the Co2 pressures at Home Depot. Never looked into it though.
