FZONE Neo CO2 Aquarium Diffuser, L-24mm for Large Tanks with Fine-Mist Ceramic

FZONE Neo CO2 Diffuser is an aquarium diffuser designed to disperse CO2 for aquatic plants, with a customized ceramic disk from South Korea and an L model for tanks of 32 gallons (121.1 L) or more.

• Microscopically small pores in the South Korean ceramic — create a fine mist that disperses through aquarium water.
• Transparent acrylic bubble counter permanently bonded to the ceramic — provides a tight fit for pressurized CO2.
• Works with CO2 systems, including DIY setups, at 20 PSI (1.37 bar) — suits a range of system types.
• Provided suction cup — secures the diffuser in an aquarium corner.
• L model: more than 3 bubbles per second for aquariums of 32 gallons (121.1 L) or more — sized for higher CO2 output and larger tanks.

Adding CO2 to an aquarium can support aquatic plant growth, and this diffuser is made to break the gas into fine bubbles that disperse through the water column. Its compact diffuser-and-bubble-counter design is intended for planted aquariums where a corner-mounted setup is useful.

How does the FZONE Neo CO2 Diffuser disperse CO2?

The customized ceramic disk has microscopic pores that produce very fine bubbles for thorough diffusion. The fine CO2 mist breaks down into the water column, where it can be absorbed by aquatic plants. The diffuser is designed to provide a high level of CO2 saturation in the aquarium.

• The ceramic disk is permanently attached to the acrylic bubble counter.
• The micro-porous ceramic produces a fine mist.

What tank size is the L-24mm model suited to?

The L model is intended for aquariums of 32 gallons (121.1 L) or more and a flow rate above 3 bubbles per second. FZONE also offers S and M models for lower flow rates and smaller tanks, so the model range covers different aquarium sizes.

• S: 1–2 bubbles per second for tanks of 13 gallons (49.2 L) or less.
• M: 2–3 bubbles per second for tanks from 13 to 32 gallons (49.2–121.1 L).

For choosing a model, match the aquarium’s capacity and intended bubble rate to these ranges.

Does it work with DIY CO2 systems, and how is it mounted?

The diffuser works with all CO2 systems, including DIY setups, and requires 20 PSI to operate; pressure above 25 PSI is recommended. Use the provided suction cup to position it securely in a planted aquarium corner.

• Transparent acrylic makes the bubble counter visible.
• The acrylic component is described as not easily broken during aquarium maintenance.
• The bonded ceramic and counter form a close connection for pressurized use.

The FZONE Neo CO2 Diffuser suits planted-aquarium keepers choosing a corner-mounted diffuser for a compatible CO2 setup, especially those with a tank suited to the L model’s flow range. Its South Korean porous ceramic, bonded acrylic bubble counter and L sizing define its use for dispersing CO2 in larger aquariums.
