Bioscape CO₂ Reactor with On/Off Valve

The Bioscape CO₂ Reactor with On/Off Valve is a versatile, efficient, and easy-to-use CO₂ generation system designed for freshwater planted aquariums. Using two inexpensive and readily available compounds—citric acid and sodium bicarbonate—this system produces a steady supply of CO₂ that can be delivered directly to your chosen diffuser (not included) for optimal plant growth and vitality.

Built with precision engineering, the kit includes a pressure vessel, pressure reducer, contents gauge, needle valve, bubble counter, and on/off valve, giving you complete control over CO₂ production and delivery.

Key Features

• DIY CO₂ Generation – Produces CO₂ using citric acid and sodium bicarbonate.

• Complete Control – On/off valve allows easy manual regulation or integration with a solenoid timer.

• Professional Components – Includes pressure vessel, needle valve, bubble counter, and regulator.

• Durable & Safe – SUS304 stainless steel cylinder with built-in safety valve for high-pressure resistance.

• Long-Lasting – One charge can last up to 60 days, depending on tank conditions.

• Precise Bubble Rate – Fine adjustment needle valve for accurate CO₂ dosing.

• Versatile Setup – Compatible with timers, solenoids, and in-line configurations for your filtration system.

What’s Included

• Pressure vessel

• Pressure reducer & gauge

• Needle valve & fine adjustment

• Bubble counter

• On/off valve

Instructions Overview

1. Combine 200g citric acid and 200g sodium bicarbonate in the reaction cylinder.

2. Tilt cylinder to 45° and add 300ml water to start the CO₂ reaction.

3. Immediately attach the regulator to begin gas generation.

4. Connect bubble counter and adjust needle valve to set the desired bubble rate.

5. Use the on/off valve for easy control or integrate with a solenoid timer.

6. Refill and maintain according to detailed instructions to ensure consistent performance.

Safety & Maintenance

• Cylinder walls may cool during reaction—this is normal.

• The system has a built-in safety valve to release excess pressure.

• Always rinse and dry components before refilling.

• 12-month warranty covers manufacturing defects (excluding misuse).
