FZONE Neo CO2 Aquarium Diffuser, M-17mm for 13–32 Gallon Tanks

FZONE Neo CO2 Diffuser M-17mm is an aquarium CO2 diffuser for distributing CO2 in planted tanks, with customized ceramic from South Korea.

• Microscopically small ceramic pores — create a fine CO2 mist for diffusion through the water column.
• Integrated acrylic bubble counter and ceramic disk — provide a closely joined assembly designed to hold under high pressure.
• Transparent acrylic construction — keeps the diffuser visible and is less prone to breaking during aquarium maintenance.
• Provided suction cup — lets you secure the diffuser in a planted aquarium corner.
• Works with CO2 systems, including DIY setups — requires only 20 PSI (1.37 bar); pressure above 25 PSI is recommended.
• Three model sizes for different tanks — the M model is for 13–32 gal (49.2–121.1 L) aquariums.

Planted aquariums need CO2 distributed into the water so aquatic plants can absorb it. This diffuser is made for that job, turning CO2 into fine bubbles that disperse through the water column. The M-17mm model is intended for the middle tank-size range and combines diffusion with a visible bubble counter in one assembly.

How does the FZONE Neo CO2 Diffuser distribute CO2?

The ceramic disk’s microscopic pores break CO2 into a fine mist, which can disperse through the aquarium water and be absorbed by aquatic plants. The diffuser is designed to provide a high level of CO2 saturation in the aquarium. Its ceramic disk is permanently adhered to the acrylic bubble counter, forming a tight fit for use under pressure.

• The M model is intended for a flow rate of 2–3 bubbles per second (bps).
• The transparent counter makes bubbles visible as they pass through the diffuser.

Which aquarium size is the M-17mm model for?

The M model suits aquariums from 13 to 32 gallons (49.2 to 121.1 L), with a recommended rate of 2–3 bubbles per second. FZONE offers three model sizes to match different tank capacities and bubble rates.

• S: 1–2 bps for aquariums of 13 gallons or less.
• L: more than 3 bps for aquariums of 32 gallons or more.

What CO2 setup and placement does it support?

The diffuser works with all CO2 systems, including DIY setups. It operates at 20 PSI (1.37 bar), with pressure above 25 PSI recommended. The included suction cup allows corner placement in a planted aquarium.

• The clear acrylic body is made to be less easily broken during aquarium maintenance.
• Choose the model by matching your aquarium capacity and desired bubbles-per-second range.

The FZONE Neo CO2 Diffuser M-17mm is suited to planted-aquarium keepers seeking a ceramic diffuser for a 13–32 gallon tank and a CO2 rate of 2–3 bubbles per second. Its South Korean ceramic, integrated bubble counter and corner-mounting suction cup bring diffusion and placement together in one unit.
