The Chihiros Manifold Block is an official extension designed specifically to expand the Chihiros Regulator Pro, allowing you to split and independently control CO2 flow across multiple aquariums from a single gas cylinder.

Key Features:

• Multi-Tank Expansion: Each manifold block adds exactly one extra CO2 outlet, allowing you to daisy-chain and power up to 4 aquariums simultaneously.
• Dedicated Control: Every individual block features its own built-in, highly precise needle valve and an easy-to-read bubble counter. This lets you tailor different bubble rates for tanks with varying sizes or plant demands.
• Standard Fitting: The output side natively fits standard 4/6 mm CO2-safe aquarium hoses.
• Streamlined Design: Blocks bolt securely directly into each other using included mounting screws, eliminating messy splitters and creating a space-saving, leak-free line.

Crucial Compatibility Warning:

Make sure you match the exact generation of your hardware before purchasing:

• The standard Chihiros Manifold Block for CO2 Regulator PRO is built for the original Chihiros CO2 Regulator Pro.
• A separate variant exists called the Chihiros CO2 Regulator Pro – Limited Edition.
• These two generations are completely incompatible with one another; parts from the original Pro series cannot be mounted onto the Limited Edition regulator and vice versa.
