Wyin Aqua Modular CO2 Extension Manifold Block (with Bubble Counter)

Running CO2 to more than one tank or diffuser usually means buying a second regulator, or using a cheap splitter that makes it impossible to balance the flow. The Wyin Aqua Modular CO2 Extension Manifold Block solves that. It attaches to the side of your Wyin Aqua modular regulator and adds another independent CO2 output, with its own needle valve and bubble counter, all running from one cylinder.

How it works

Each block takes CO2 from the regulator, or from the block before it, and sends it out through its own needle valve and bubble counter. Turn the knurled needle valve knob to fine-tune the flow, then watch the bubble counter to see exactly what each tank is getting. Adding another tank later? Add another block to the chain.

Why you'll like it

• One cylinder, multiple tanks. Run separate CO2 lines from one regulator and one cylinder.
• Set each tank separately. Every output has its own needle valve for precise control.
• See the flow at a glance. The built-in bubble counter shows the bubble rate on each line.
• Grows with your setup. Add more blocks whenever you add another tank.
• Built to last. Machined anodised aluminium with a matte black finish.

Compatibility

Designed only for the Wyin Aqua Dual Gauge Smart CO2 Modular Regulator and the Wyin Aqua Dual Stage Smart CO2 Modular Regulator. It won't fit other regulators.

Specifications

• Material: anodised aluminium, matte black
• Needle valve: knurled knob, turn clockwise to close
• Bubble counter: built in, clear chamber
• Flow direction: marked with an arrow on the block

What's included

• 1 x extension manifold block with needle valve
• 1 x bubble counter
• 2 x connecting pins
• 1 x hex key

Installation

1. Turn the CO2 off at the cylinder and release the pressure from the regulator.
2. Line the block up with the side of your regulator's manifold, or the last block in the chain, with the arrows pointing the same way.
3. Fix it in place using the included connecting pins and hex key.
4. Screw the bubble counter onto the top of the block, fill it with water and connect your CO2 tubing.
5. Close the needle valve fully, turn the CO2 back on, then open the valve slowly until you reach the bubble rate you want. Check all joins for leaks with soapy water.
