描述

Enhance your planted aquarium with the Wyin Aqua Citric Acid CO₂ System (1 L). This premium kit substitutes cumbersome high-pressure gas cylinders with a safe, efficient citric acid + baking soda chemical reaction housed in a robust stainless steel vessel. Ideal for nano to medium tanks, this 1 L version delivers reliable CO₂ output, full regulator control and finish-level components.

What’s included in the kit

  • 1 L polished stainless steel CO₂ generator cylinder
  • Precision CO₂ regulator with gauge & needle valve
  • 12 V DC solenoid valve for on/off control (timer compatible)
  • Aluminium bubble counter with integrated check valve
  • Ceramic CO₂ diffuser for fine CO₂ dispersion
  • 2 m CO₂-resistant tubing (4/6 mm)
  • U-bend tube holder for neat tank placement
  • Suction-cup holder and mounting hardware

Instructions for use (for 1 L version)

  1. Add 140 g citric acid + 160 g baking soda into cylinder.
  2. Pour in 200 ml water carefully (tilt cylinder to minimise foam).
  3. Attach regulator and watch pressure build.
  4. Prime bubble counter with water (~¾ full), connect tubing and diffuser.
  5. Secure tubing around rim with U-bend tool, set bubble rate.
  6. For best results: 0.5–1 bubble/second is a good start for moderate setups; adjust as plants respond.
