Hi everyone,
I'm looking to purchase a 2kg co2 cylinder for my 125 litre Juwel Rio. This is mostly due to the fact that my Aqua One Nano co2 set is terrible - 95g doesn't last long and the diffuser and co2 tubing fill up with water overnight resulting in my having to take apart my kit every single morning and putting everything back together before I start injecting.
I've been talking to a company that sell cylinders but there's some terminology that I don't quite understand in their email and I can't find a sufficient explanation with Google, so I though I'd ask the experts.
Their email reads as follows:
"We have supplied 2kg Co2 cylinders for use with aquariums before, we can supply a 2kg Co2 cylinder c/w a screw down valve for £48.00 plus vat (£57.60)
The unit will be a fully tested unit and come with a test certificate which is valid for ten years. After ten years the cylinder will need testing and the valve replacing.
Refill costs up to the ten year date are £5.00 including vat (if you bring the cylinder to us, can usually be filled whilst you wait if cylinder is in test).
The price for the cylinder includes delivery if we can deliver when next in your area, if we need to make a special trip we would need to charge for delivery (£15.00)
The valve will have a dip tube fitted which means that the liquid co2 is discharged as opposed to a welding cylinder where no dip tube is fitted and just the Co2 vapour is used (this is the set up for most welding applications).
You can have either option please advise which you would prefer."
My questions are:

My questions are:
- What is a screw down valve, and do I need one?
- Will I need a dip tube or should I got with a welding cylinder instead with no dip tube?
