Dual Stage Regulators

[Left C]

Over the past year or two, there has been quite a stir regarding two stage regulators. Many people have been able to purchase a new or used two stage regulator from individuals, as closeouts, yard sales, from ebay, and other places. Together with a solenoid, bubble counter and very good needle/metering valve found the same way, many people have been able to assemble their own high quality CO2 regulator for planted and saltwater aquariums at a very reasonable cost. Two stage regulators will continue to hold their working pressure steady until the CO2 cylinder is empty unlike single stage regulators which will increase their working pressure when the cylinder nears being empty. Sometimes, dire circumstances can occur.

Some information that will be found here are the differences between single and two stage regulators, how to build your own regulators, where the deals are, what works great and what doesn't plus anything else that we want to discuss. Part numbers for many items will be given. If you know about vendors that are having a sale, feel free to post it.

Unlike some places, you may leave ebay links and post information. They are welcome.

You may post pictures of your regulator, your DIY assembly guide, parts, etc.

There is already a place on this forum where you may want to trade, swap or sell: http://www.barrreport.com/trades-swaps-sales/

This thread is for everyone to feel free to join in and discuss, add to or to question. In the beginning, there will be information that some people may have seen already, but it will be helpful for new people.


EDIT: The Victor thread at TPT isn't a sticky anymore. This is the link to it. It is going to be kept closed.
