That’s the safest way of doing it.
Beer gas cylinders aren’t expensive though the last time I looked but it can vary a bit.
Just because you haven’t had a problem so far means nothing. And forget about claiming on your insurance if anything should go awry as you’re using something for a...
I mentioned some years ago that I was told by a guy who services them that it’s not something he would use a fire extinguisher for. He explained that the valve was regarded as single use and that once activated it was not expected to be leak proof. I expect he must know more about the subject...
I admit I’ve only bought easy to grow plants from Tropica but they grow like mad without any CO2 in my 60L and 37L Nano’s. I regularly have to trim the plants to stop them overgrowing. I don’t even add much in the way of liquid fertiliser either. It’s a mystery to me why the plants grow so well...
I know I’ve only got a few easy to grow plant types in my two Nano’s but I don’t have any CO2 and the plants grow like mad. Substrate is just sand as well.
It’s a little over budget and spec but what about this?

I really like Dennerle stuff and have had a couple of tanks from them.
I personally wouldn’t have a CO2 system in a bedroom to start with. I’ve not heard of anyone dying from a leaky system but there’s always a first time.
Thats good news.
When I looked at pictures of some of their past regulators they seem to have used a variety of different parts for the outlet.
How old is your regulator?
Looking at some other CO2 regulators they call that part a Pisco valve, some suppliers call it a PSCO valve. Try a google search and you’ll get something like this. You need to know the tubing size and the thread size in the regulator. BSP threads are popular for these sort of things. This may...
As far as I am aware they all work pretty much the same way. They are made in different styles and of different materials. I think the glass ones are likely to be easier to clean though if they get dirty. My old plastic Dupla one got calcium deposits on it which were difficult to remove.
As...
Have you seen item number 153393279391 on the auction site? Only £1.45 and no need to get you hands wet as the main part hangs outside the tank. You just need to get some solution to go with it.
Yes the Marine side as you put it do have some nice tech. Although I’m more interested in low tech I do rather like the look of the control and monitoring app available for the iPad.
Yes, I like gadgets too. I bought this to hook up to the last canister filter I had but never got round to using it. Bought from China on the auction site for not much money.
You can get electronic ones now too of course...
Something like this?

I bought something similar but for water and it was quite a good price on the auction site.
If you check out the Machinemart website they sell this 600g one for £14.39:

And this 390g one for £13.19:

Strange indeed!
If you look at the picture it says on the bottle:
SAME SIZE BOTTLE WITH 54% MORE GAS.
I assume this is done with higher pressure? I think I’ve seen both 36 bar and 55 bar mentioned for these cylinders.
There seem to be so many sources for smaller non standard CO2 bottles like welding and paintball bottles. I wonder which actually works out the cheapest in the end. I understand that not everyone wants a pub CO2 bottle or fire extinguisher in their lounge!
I’m not talking about Co2 dead spots, that would be silly. I’m talking about water flow dead spots. I noticed this on my old 50 gallon Freshwater setup years ago so yes, from personal experience you can get dead spots.
I used to get round this by altering the angle of the outflow from time to...
I did read many years ago that you get dead spots in the tank with a constant flow. A German system I saw was set up so that it would flow in one direction for a set time then automatically switch directions with a timer. I’ve no idea how the plumbing was set up to achieve this as it was a long...
Deionised water is freely available in supermarkets so I'd use that if I couldn't already get distilled water for free. Given the potential hazards I'm not sure I'd be happy boiling even a dilute solution of Glutaraldehyde but I'd be interested in reading the data! :lol:
I would have thought Easy Carbo and Excel are just diluted with Distilled Water but maybe there is something else in the bottle?
Hopefully it's just water movement and oygen that causes it to break down in the Aquarium. :?
Questions, questions!
Shame we can't ask the guys who pioneered the...
It's a bit of a frustrating subject as there seem to be several different fittings used. JBL I think use 10x1mm thread. Disposable (welding) CO2 bottles are reckoned to be 1/8 BSP and ADA use something else. Full size CO2 in the uk are BS341 No 8 or DIN 477 in EU. The US have CGA 320 and Japan...
I've read that concentrated Glutaraldehyde can be quite nasty stuff if handled incorrectly. Don't quote me but I think they use a 5% solution in commercial plant products like Excel.
I'm not sure I'd be happy handling stronger solutions without more information.
This stuff is 50%...
We have hundreds of FE's where I work. When we've changed suppliers in the past the incoming company has been happy to let me have a couple of CO2 FE's so when I first read about using them on an aquarium it was a no brainer. I asked someone from the fire safety company first though and they...
From the top of the stem apparently.
But why would you take the risk?

Once you've got the first cylinder it's only £16.80 for a refill. And thats for 3.15Kg not 2Kg in a FE thats likely to cost you over £25?
Is it worth it to save a few...
Not true. And this from the horses mouth "The valve is only expected to be leak free in the closed position. A small amount of leakage whilst it's held open would not be regarded as a problem as a large amount of CO2 is already being vented to atmosphere fighting a fire"
The valve on the top of a Fire Extinguisher is completely different to that on say a beer gas cylinder (which is a better option IMO) It's designed to contain the gas in the cylinder until needed then release it quickly in one or more bursts - it's not designed to be kept open for several...
A correctly installed system, with care taken to ensure there are no leaks should be quite safe. You must be aware though that there is a very real risk of Carbon Dioxide Asphyxiation if a substantial leak should occur in a confined space.

It would really help to know exactly what rate(s) of flow are actually needed. I'm sure someone out there makes exactly what we need at a reasonable price if only we can ask the right question.
Anyone care to take a stab at flow rates in cc per minute of Co2 or some other suitable measurement?
Although it's perfectly possible, it may not work that way. If you can get a second valve at a good price then give it a try. If it works be sure to let us know!
I don't know enough about metering valves for our low flow CO2 application, I wish I did.
I've been doing some research on the subject...
Putting a second needle valve on a possibly faulty one doesn't sound like a good idea. If the original valve is not part of the reg then maybe you could just replace it. Failing that maybe the valve just needs some seals replaced?
Not sure if this has been done before. I'll start.
Here's mine, an old Distillers CO2 model with a Dupla needle valve. I'm not using CO2 at present but I'd retire this in favour of something newer if I was! Needle valve is good though.
German and Dutch shops sell the Dupla stuff. Nice looking Reg for the price:

I'm not sure if I'm looking at the right one but the Lunapet looks like a simple single stage welding reg...
Yes, the Dupla stuff is good. I have one of their old needle valves like this one but mine doesn't have the gauge.
http://www.okazii.ro/pesti/reductor-co2 ... -a52475951
Eight turns from fully closed to fully open. Think I may get a gauge for it.
Some other folks have tried them.
http://i817.photobucket.com/albums/zz92 ... G_4792.jpg
But I think they are a bit pricey and as I don't think the Swagelock ones are made in the UK the threads on them may be an issue? I'm not too sure but believe the US use NPT threads and here in the UK we...
Well you did say "Best Reg" so I found you this:
http://www.fnpile.co.uk/index.php?area= ... ct_id=1991
This is clearly not a cheap welding reg like some of those offered but it will cost you about £110 plus vat. Not bad for such a high quality piece of kit and you did say "regardless of cost"...
Ten inch water filter casing.

They come in several different inlet/outlet thread sizes and adaptors are available.
Atomisers have very fine holes so yes, whilst it's been turned off they could have become blocked. Try another atomiser to be sure. Be interesting to know if they can be cleaned effectively?
It's only a thought but I can't help thinking it would be better if the needle valve bolted straight into the regulator? There seem to be quite a number of threaded adaptors about if it's not a direct fit.
Wherever possible use bonded (Dowty) washers or thread sealant to prevent leaks.
Good...
There are lots of different pressure couplings available. Could'nt say what you need without knowing what threads you have. When I needed adaptors I went to the experts - the trade counter of a local supplier. They can tell just by looking exactly what you need.
I would expect that as paintball is relatively new everyone would have adopted the original American fitting, but you never know ... Hope it works out, let us know how you get on!
Re: Fire extinguisher lifespan
I wouln't have thought so. Whenever they "service" the co2 extinguishers at work all they do is weigh them to see if they're full.
You've certainly done your homework! Not sure about the reg, especially the fitting. Looks like it's for disposable bottles so won't fit the FE directly. The rest looks good though. Check out item 270720304764 on the bay, only a quid more and it fits directly on the solenoid so it'll look neater.
Several names for the tool but often called a pin spanner. Some are adjustable for spread or you can get hex bits for the small sizes.
