Here’s all about the MUFAN CO2 Regulator with Solenoid — a popular choice among planted tank hobbyists for safe, precise, and automated CO₂ injection:

🔍 MUFAN CO2 Regulator with Solenoid: Overview

The MUFAN CO₂ Regulator with Solenoid is designed specifically for freshwater planted aquariums. It regulates CO₂ gas from a pressurized cylinder and automates its release using a solenoid valve, helping plants grow lush and healthy by providing a stable carbon source.

🔧 Key Features

• ✅ Dual gauge display:

  • One gauge shows tank pressure (in psi/bar).

  • The other shows working/output pressure.

• ✅ Integrated 220–240V solenoid valve:

  • Allows timer-controlled CO₂ injection (on/off).

• ✅ Fine-tuning needle valve:

  • Enables precise control of CO₂ bubble rate.

• ✅ Durable brass body:

  • Corrosion-resistant and built to last.

• ✅ Thread compatibility:

  • Fits standard CO₂ cylinders (W21.8 or CGA320 versions available depending on region).

• ✅ Plug-and-play design:

  • Easy for beginners to set up.

✅ Benefits

• Automated CO₂ control: Solenoid can be synced with a timer to turn off at night, saving gas and preventing CO₂ build-up.

• Improves plant growth: Ensures a stable CO₂ supply for photosynthesis.

• Energy efficient: Low power consumption solenoid (often under 5W).

• Safe operation: Reduces risk of over-pressurizing or inconsistent gas flow.

• Beginner-friendly: Clear gauges and smooth valve control.

⚙️ Typical Setup

1. Attach regulator to a pressurized CO₂ cylinder.

2. Connect to bubble counter + check valve + diffuser using CO₂ tubing.

3. Plug solenoid into a timer or pH controller.

4. Adjust needle valve to set desired bubble count (e.g., 1–2 bubbles/sec for mid-size tanks).

🔋 Solenoid Details

• Operates on standard AC power (India: 220–240V).

• Can be linked to:

  • A digital timer (to inject CO₂ only during photoperiod).

  • A pH controller (to maintain specific CO₂-related pH levels).

• No heat or buzzing if functioning properly.

🛠️ Maintenance Tips

• Regularly check and tighten connections to prevent leaks.

• Replace or clean the needle valve if it becomes stiff or inconsistent.

• Bleed pressure from the regulator before detaching from cylinder.

• Avoid using oil or grease near CO₂ parts.

⚠️ Safety Precautions

• Always turn the main tank valve slowly.

• Never exceed recommended working pressure (usually under 40 psi).

• Use only with approved CO₂ cylinders.

• Place regulator in a well-ventilated area.

📦 What’s Usually Included

• Dual-gauge CO₂ regulator.

• Built-in solenoid valve.

• Needle valve.

• CO₂ tubing (sometimes included).

• Instructions manual.

🛒 Ideal For:

• Aquarists with planted tanks (10–200+ liters).

• Those wanting automated CO₂ injection.

• Hobbyists looking for a budget-friendly but reliable setup.
