Aquarium CO2 Equipment, Regulators & Diffusers

Shop aquarium CO2 equipment at The Tech Den Australia for freshwater planted tanks and aquascaping setups. Explore regulators, diffusers, CO2-resistant tubing and monitoring accessories from AquaLabs, CO2 Art, Aquario, Dymax, Dalua, Fluval and Seachem.

Build or upgrade your CO2 setup

  • Regulators and control: dual-stage regulators, solenoid-equipped models, compatible controllers and manifold extensions.
  • CO2 diffusion: in-tank glass, acrylic and stainless steel diffusers, inline atomisers and reactors.
  • Monitoring and connections: drop checkers, indicator solution, bubble counters, check valves and CO2-resistant tubing.
  • Replacement supplies: model-specific diffuser discs, regulator washers, disposable cartridges and reactor reagents, plus empty CO2 cylinders.

Check compatibility before ordering

Match your regulator to the cylinder connection and mounting type. Check diffuser working-pressure requirements, recommended tank size and tubing dimensions. Inline diffusers include options for 12/16mm and 16/22mm filter hoses; select the size that matches your system. Confirm what is included with each product rather than assuming every item is a complete kit.

Follow the manufacturer's installation and operating instructions, and use suitable monitoring equipment when adjusting your setup. Check individual listings for delivery restrictions: selected Fluval disposable CO2 cartridges require road freight and cannot be sent by express shipping. Cylinders labelled empty are supplied without gas.
