CO2 diffusers do not need to be inside your aquarium! Now Aquasabi offers a CO2 diffuser that attaches inline to your canister outflow. This means less devices inside your tank and therefore a more natural look and more space for plants and animals to prosper.

Unlike many other inline reactors, the inline diffuser disperses CO2 with minimal reduction in flowrate. The unit also has two built-in attachment points for detachable suction cups and can be securely attached to the side of the tank. The two suction cups are included.

  • One less equipment inside your aquarium
  • Enhanced CO2 dissolution via turbulent mixing
  • Minimal reduction in flow compared to many CO2 reactors
  • Creates a fine mist of CO2 shown by many to further enhance plant growth
  • Reduce photosynthetic algae growth on diffuser disc when placed away from direct light (ie. outside of tank or inside tank cabinet)
  • Active flow around diffuser prevents debris buildup on diffuser disc

  • Install the diffuser in the outflow line of the canister filter according to the diagram below. The diffuser can be attached up high next to the aquarium, or down below inside the cabinet. Use a high-quality check-valve
  • CO2 from a pressurized source is recommended
  • Always wet glass surfaces before fitting tubing. Tubing can be soften by dipping in hot water
  • To prevent damage to glassware, do not use excessive force when fitting or removing tubing. We strongly recommend using soft silicone tubing for all glassware
  • Do not shake or tap the diffuser against hard surfaces

We recommend to use soft silicone tubing to connect the glassware in order to reduce the risk of glass breakage. The piece of hose used should be kept as short as possible in order to avoid unnecessary CO2 losses.
Silicone hose is not pressure resistant and therefore can not be used for connection to the pressure regulator.

Cleaning and Maintenance

  • Prepare a 1:1 mixture of bleach to water

  • Rinse several times with clean running water before connecting back to the aquarium
