The UNS Pro CO₂ Manifold Block is an add-on extension designed to clip directly onto your existing UNS Pro Dual Stage Regulator. By stacking these modular blocks together, you can split your carbon supply to feed multiple independent aquariums from just one gas cylinder. It is an incredibly smart, clean, and cost-effective way to expand your layout, giving every display tank, shrimp home, or prop rack the exact, dedicated carbon support it needs to stay lush and algae-free.

Key Features & Benefits

  • The modular, stackable design allows you to expand your gas distribution to as many tanks as you want from a single central cylinder.
  • An ultra-precise needle valve gives you completely independent control over the bubble count for each individual aquarium connection.
  • An integrated bubble counter and check valve combo provides visual flow tracking while safeguarding your shared hardware from water backflow.
  • A simple, leak-proof mounting setup ensures a secure attachment to your main regulator body without complicated plumbing or tools.

Product Specifications

  • Regulator Compatibility: Designed exclusively for the UNS Pro Dual Stage CO₂ Regulator
  • Integrated Safety: Built-in mechanical check valve protection
  • Material: Precision-Machined Premium Alloy

This listing includes one separate add-on manifold block only. The main UNS Pro Dual Stage Regulator and gas cylinders are sold separately. Add one extra manifold block for every additional aquarium you want to power!

Reviews

Works great

"I was initially stymied by the manifold. The brass piece had originally been placed on the wrong side of the manifold. Eventually, I discovered that the brass piece was removable. A quick switch to other side fixed the problem."

Easy to install

"This whole system is fantastic! I purchased the first kit that came with two, then added two more. They are amazing and so precise with the needle adjustment valve. Some valves are so hard to fine tune, but this one is easy!"

CO2 Purchase

"My 3 business day delivery ended up taking over two weeks to arrive. Customer service responded within 24 hours which was great, but I feel like if I never reached out, I never would have received my package. Once arrived, everything was neatly and tightly packaged. It appeared new and in great condition. I’d consider ordering live goods from them, but definitely not till spring due to the shipping delay."

— Stephen S. (4/5)

Q&A

Can I add more than one output or is it only good for 2????
Hi Luis, Thank you for your question! The UNS Pro Dual Stage CO2 Regulator allows for up to three additional manifold blocks to be added. This gives you a total of four output ports for multiple aquarium CO2 injection setups. Best regards, Team Buce Plant
Can this manifold be used with the mini regulator?
Hello Juan, thank you for your question. Unfortunately, these manifold blocks will not be compatible for the UNS Mini Regulator, as there wouldn't be a connection for the block on the Mini Regulator. If there is anything else I can assist you with, please email us at support@buceplant.com. Thank you, Team Buce Plant
How many manifolds can be added to a UNS Pro System regulator in addition of the included two?
Hi Brandon, Thank you for reaching out to us. We would recommend not putting more than 4 manifolds onto a single regulator. Feel free to contact us at support@buceplant.com for any questions or concerns. We are always happy to help! Best regard, Buceplant Team
Would these be compatible with Milwaukee solenoids? MA955?
Hi Eric, Thank you for reaching out to us! We are not familiar with how the Milwaukee solenoids is built and can not say for sure if the UNS Pro CO2 Manifold Blocks will work or not. They are designed to fit onto the UNS dual stage regulators, so we can not assume that they fit other regulators. If you have any additional questions or concerns, please do not hesitate to contact us at support@buceplanthelp.zendesk.com. We are always happy to help! Best Regards, Buceplant Team
