Bioscape CO₂ Reactor with Solenoid

The Bioscape CO₂ Reactor with Solenoid is a professional-grade 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, controlled supply of CO₂. The gas is then delivered via tubing to your preferred diffuser (not included), ensuring optimal growth, color, and vitality of aquatic plants.

Equipped with a pressure vessel, pressure reducer, contents gauge, needle valve, bubble counter, and electronic solenoid, this kit allows precise regulation of CO₂ output, perfect for integration with a timer or automated lighting schedule.

Key Features

• DIY CO₂ Production – Uses citric acid and sodium bicarbonate to generate CO₂ economically.

• Electronic Solenoid Control – Automate CO₂ dosing with your aquarium’s lighting schedule.

• Complete Control – Fine adjustment needle valve and bubble counter for precise dosing.

• Durable Construction – SUS304 stainless steel cylinder with built-in safety valve withstands high pressure.

• Long-Lasting Charge – One reaction can last up to 60 days at approximately one bubble per second.

• Safe Operation – Safety valve prevents over-pressurization; cylinder cooling during reaction is normal.

• Versatile Setup – Can be used with manual on/off valve or integrated with solenoid timers.

What’s Included

• Pressure vessel

• Pressure reducer & gauge

• Needle valve with fine adjustment

• Bubble counter

• Electronic solenoid

• Refill and setup instructions

Operation Overview

1. Place 200g citric acid and 200g sodium bicarbonate into the reaction cylinder.

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

3. Immediately attach the regulator to initiate CO₂ production.

4. Fill the bubble counter and connect it to the fine adjustment valve.

5. Connect solenoid to a timer; the indicator light signals when CO₂ is flowing.

6. Adjust bubble rate with the needle valve for precise CO₂ dosing.

Safety & Maintenance

• Built-in safety valve releases excess pressure.

• Cylinder walls may cool during reaction—normal operation.

• Rinse and dry components thoroughly before refilling.

• 12-month warranty covers manufacturing defects; mechanical damage caused by misuse is excluded.
