- Splits CO2 between multiple aquariums
- Individually adjustable CO2 output
- Easy to install
Easily run CO2 from one cylinder to multiple different aquariums using expansion manifold blocks. These handy manifolds screw into the existing CO2 regulator system and to each other for the ability to link up to 5 expansion manifold blocks together (for a total of 6 aquariums connected to one CO2 cylinder). Simply add one block for each planted aquarium you'd like to inject CO2.

Customer Reviews
When I heard that Cory might not be selling the CO2 regulators any more I knew I had to snap up at least 1 more expansion manifold. I love the regulator and manifolds Cory made and they are quality pieces of equipment. Hope he keeps at least offering the expansion manifolds!
Great regulator. I love that I can add manifolds for relatively cheap and add to the system. I do wish the mating surface for the tank was made of steel, as I over tightened it some and chewed up an o ring and scared the aluminum some. That's not the fault of aquarium co-op though, just me. I'll be adding another tank in a separate room this summer and I'll be purchasing another regulator when I do.
I wanted to add another tank to my aquarium coop regulator and this does exactly what is says!
We have purchased 2 regulators, both stopped working within 2 weeks. It’s a total bummer because the design is great but there appears to be something wrong with some of the actual regulators.
The great thing about Aquarium Co-op is they will honor their 1 year warranty.
Allows better expansion to other systems!
Product works very well. This is the first CO2 system I set up and I had a few setbacks along the way. Aquarium co-op is 3000 miles from my house but they were right there for me every step of the way. This is why I will gladly pay shipping to give them continued support.
What can I say. This just like all there products are great. Long lasting and great prices. Thx coop
Well made. No leaks and easy to install.
Perfect! Just what I needed!
This is a great value and the unit has a matching finish to the regulator. Thank you Co-Op for keeping the price reasonable!
