Description
Co2 Aquarist Ultimate Manifold Extension
The CO2 Aquarist Ultimate Manifold Extension is an accessory designed to expand the functionality of the CO2 Aquarist Ultimate Dual Stage Regulator, allowing precise CO2 injection into multiple planted aquariums from a single CO2 cylinder. It integrates seamlessly with the regulator, enabling aquarists to customize CO2 dosing for up to five additional tanks (six total, including the primary manifold). Each extension includes a bubble counter, check valve, and high-precision needle valve, ensuring independent control and reliable performance for planted aquarium setups.
Below is an example of two additional manifold extensions

Benefits:
- Multi-Tank CO2 Delivery: Enables CO2 injection into multiple aquariums (up to six) from one cylinder, reducing the need for multiple regulators and saving space and cost.
- Independent Control: Each manifold extension has its own needle valve and bubble counter, allowing tailored CO2 dosing for each tank’s specific needs.
- Enhanced Plant Growth: Supports optimal CO2 levels (25–35 ppm) across multiple tanks, promoting lush plant growth and outcompeting algae for nutrients.
- Safe and Stable: Built-in check valve prevents water backflow, and the robust design ensures consistent CO2 output, minimizing risks to livestock.
- Cost-Effective Expansion: Adds functionality to an existing regulator without requiring additional cylinders or full CO2 systems.
- High-Quality Construction: Made from stainless steel and aluminum alloy, ensuring durability and corrosion resistance for long-term use.
Features:
- Modular Design: Attaches to the CO2 Aquarist Ultimate Dual Stage Regulator, with the ability to add up to five manifold extensions for a total of six outputs.
- High-Precision Needle Valve: Allows fine-tuned CO2 dosing as low as 1 bubble per 10 seconds, suitable for nano to large tanks.
- Integrated Bubble Counter: Provides a visual indicator of CO2 flow rate for each tank, simplifying monitoring and adjustments.
- Built-In Check Valve: Prevents water from siphoning back into the regulator, protecting the system from damage.
- Robust Materials: Constructed from high-grade aluminum alloy and stainless steel for durability and resistance to corrosion.
- Easy Installation: Includes mounting screws and an Allen wrench for straightforward attachment to the regulator or additional manifold blocks.
- Compatibility: Designed specifically for the CO2 Aquarist Ultimate Dual Stage Regulator, ensuring seamless integration.
How to Use:
1. Gather Required Components
- CO2 Aquarist Ultimate Dual Stage Regulator (base unit).
- CO2 Aquarist Manifold Extension(s) (one per additional aquarium, up to 4).
- CO2 cylinder compatible with AU/NZ W21.8 European standard threads.
- CO2-resistant tubing (e.g., 4/6 mm hose).
- CO2 diffuser(s) for in-tank delivery system for each aquarium.
- Tools: Allen wrench (included with the manifold).
- Optional: Timer for solenoid automation, pH/KH test kit for monitoring CO2 levels.
2. Installation
Safety Note: Ensure the CO2 cylinder is turned off before starting. Work in a well-ventilated area, and keep the system away from heat sources or direct sunlight.
Attach the Manifold Extension:
- Unscrew the end joint (terminal cap) of the existing regulator or previous manifold block using the provided Allen wrench.
- Check the O-ring in the middle joint of the manifold extension to ensure it is correctly placed and in good condition to prevent leaks.
- Align the new manifold block with the regulator or previous block’s front joint.
- Secure the manifold block by inserting and tightening the provided mounting screws clockwise with an allen wrench.
- Repeat for additional manifold blocks if connecting multiple tanks (up to 4 extensions).
- Reattach the end joint to the final manifold block to seal the system. Ensure the end joint (without a small hole) is used, not a middle joint.
Connect Tubing and Accessories:
- Attach CO2-resistant tubing (4/6 mm) to the manifold’s output port.
- CO2 diffuser installed in the aquarium.
- Ensure all connections are secure to prevent leaks.
Connect to Solenoid: Plug the solenoid it into a timer synced with your aquarium lighting (e.g., start CO2 2–3 hours before lights turn on and stop when lights turn off). This conserves CO2 and aligns with plant photosynthesis cycles.
3. Setup and Calibration
Turn On the CO2 Cylinder: Slowly open the CO2 cylinder valve to pressurize the system. Check the high-pressure gauge to confirm gas availability.
Adjust Output Pressure:
- Set the regulator’s working pressure to 25–40 PSI using the main valve, which is safe for most diffusers.
- Fine-tune CO2 flow for each aquarium using the manifold’s high-precision needle valve. Aim for a starting bubble rate of approximately 1 bubble per second per 50 liters of tank water. For high CO2 saturation, increase to 4–5 bubbles per second, but monitor closely.
Monitor Bubble Counter: Observe the bubble counter on each manifold to ensure consistent CO2 flow. Adjust the needle valve to achieve the desired bubble rate for each tank.
Check for Leaks: Apply soapy water to connections and look for bubbles to detect leaks. Tighten connections if necessary.
4. Monitor CO2 Levels
- pH Drop Method: Use a pH/KH test kit to measure CO2 levels. Aim for a 1-point pH drop from when CO2 is off to peak saturation (typically 25–35 ppm CO2 for plant growth). Adjust the needle valve gradually, as there may be a lag in CO2 saturation.
- Observe Livestock: Monitor fish and invertebrates for signs of stress (e.g., gasping at the surface), indicating excessive CO2. Reduce the bubble rate if needed. Introduce animals when CO2 is off (e.g., after a water change) to allow gradual adjustment.
5. Maintenance
- Regular Checks: Inspect the bubble counter, check valve, and tubing for blockages or wear. Clean with a damp cloth and avoid using solvents.
- Cylinder Refills: Monitor the inlet pressure gauge to estimate when the CO2 cylinder needs refilling (typically every 4–6 months for a 3kg cylinder on a 160 litre tank).
- Solenoid Operation: If using a solenoid, ensure it shuts off CO2 when not needed to prevent overuse and maintain safety.
- Dust Prevention: Cover the regulator when not in use to avoid dust buildup, and clean with a blower if necessary.
Tips for Success
- Start Low: Begin with a low CO2 injection rate and gradually increase while monitoring pH and livestock to avoid overdosing.
- Sync with Lighting: CO2 is only needed during photosynthesis (when lights are on). Use a solenoid timer to automate injection for efficiency.
- Compatibility Caution: While manifold blocks from different brands may look similar, compatibility with the CO2 Aquarist regulator is not guaranteed. Stick to CO2 Aquarist manifold extensions for reliability.
- Plant Growth: Expect faster, healthier plant growth with vibrant coloration, as demonstrated in experiments where CO2-injected tanks showed superior growth compared to non-CO2 tanks.
Warnings
- Indoor Use Only: The system is designed for indoor use to avoid temperature extremes or condensation issues.
- Livestock Safety: Over-injection of CO2 can lower pH and harm fish. Always monitor and adjust gradually.
- Professional Installation: Some steps (e.g., manifold attachment) may require care to avoid damaging O-rings or joints. If unsure, consult a professional or the manufacturer’s service team.
