ANS PRO II CO2 Extender Manifold

ANS PRO II CO2 Extender Manifold

The ANS PRO II CO2 Extender Manifold features an integrated high precision needle valve and bubble counter. It’s optional to add or remove additional manifold as needed, and the flow rate can be adjusted as low as 0.3bps.
Includes a built-in check valve to prevent backflow of water into the regulator. It is compatible with standard 16mm CO2 proof tubing and should only be filled with freshwater. Do not use oil or salty water. With expansion manifold, you can easily distribute CO2 from one cylinder to multiple aquariums. Easily screw into the CO2 regulator and can be linked together.
You can attach the CO2 Extender Manifold to CO2 Regulator Advance from 1 to 6pcs.

ANS PRO II CO2 Extender Manifold for Multi-Tank Singapore Setups

This extender manifold lets one CO2 cylinder feed several planted tanks, each with its own integrated needle valve and bubble counter. You can add or remove manifold blocks as your setup grows, and the precision valve dials flow down to around 0.3 bubbles per second for nano scapes. A built-in check valve guards against water siphoning back toward the regulator, and it accepts standard 16mm CO2-proof tubing.

For the rack-style aquascapes increasingly common in Singapore flats, this is the tidy way to run a row of tanks off a single bottle rather than buying a regulator each. Each line tunes independently, so a demanding high-light scape and a gentle low-tech tank get exactly the CO2 they need. Fill the bubble counters with freshwater only, never oil or salt water, and check valves before refilling your cylinder so a quiet leak does not empty the bottle overnight.
