  • Fine mist that actually dissolves
  • Sized for tanks under about 20 litres
  • At home in betta and shrimp tanks
  • Clear glass disappears in the scape
  • Suction cup included

Built for tanks under roughly 20 litres, where a full-size diffuser looks like a chimney in the scape. The nano-pore ceramic disc turns CO2 into a fine mist that dissolves in a short water column instead of racing to the surface.

Description

Chihiros Nano CO₂ Diffuser (Tiny) – Glass CO₂ Diffuser

The Chihiros Nano CO₂ Diffuser (Tiny) is the smallest in the range, built specifically for nano aquariums, betta tanks, shrimp tanks, and desktop planted setups where a standard-sized diffuser would look oversized and clunky. It turns pressurized CO₂ into a fine, steady mist scaled to match a small volume of water.

What Makes It Different

At its core is a nano-pore ceramic disc that produces a dense, mist-like stream of micro-bubbles rather than a handful of large ones — important in a small tank, where the water column is too short for large bubbles to dissolve before reaching the surface. Fine bubbles give CO₂ far more time and surface area to dissolve, so more of it actually reaches your plants instead of escaping into the air.

The body is laboratory-grade glass in a minimalist design, sized to disappear into a nano aquascape rather than dominate it. It's typically supplied with a suction cup for secure, discreet placement against the glass.

Key Benefits

  • Ultra-fine ceramic disc produces mist-like micro-bubbles suited to small water columns
  • Compact, minimalist glass design built specifically for nano tanks
  • Sized for aquariums under roughly 20 litres — betta tanks, shrimp tanks, and desktop scapes
  • Compatible with standard CO₂ tubing and Chihiros regulators and bubble counters
  • Included suction cup for secure, low-profile attachment

Who Should Use This

  • Nano aquarium keepers running pressurized CO₂ on tanks under roughly 20 litres
  • Betta and shrimp tank owners wanting efficient CO₂ diffusion without oversized equipment
  • Desktop and small aquascape builders who want CO₂ hardware that stays out of the visual foreground

For tanks larger than roughly 20–40 litres, the S or M sizes handle a bigger CO₂ throughput more efficiently — a Tiny diffuser pushed beyond its intended volume will struggle to keep pace.

How to Use

  1. Soak the diffuser in clean water for around 30 minutes before first use to fully saturate the ceramic disc
  2. Connect your CO₂ tubing securely to the diffuser inlet
  3. Attach the diffuser to the tank glass using the suction cup
  4. Adjust your CO₂ regulator to produce a steady, fine mist rather than large intermittent bubbles

Maintenance

Clean the ceramic disc periodically to prevent clogging — algae and mineral buildup are the usual causes of larger, less efficient bubbles over time. A dilute bleach solution (roughly 1:10) soak for about 30 minutes, followed by a thorough rinse, restores most diffusers to like-new performance. Handle the glass body gently, as it's more fragile than plastic or acrylic alternatives.

Expert Tip

In a nano tank, small changes to CO₂ dosing have an outsized effect compared to a larger aquarium — the water volume is small enough that overshooting is easy. Start conservatively and increase gradually while watching fish behavior, since betta and shrimp tanks are especially sensitive to CO₂ swings.

Frequently Asked Questions

What tank size is the Tiny diffuser suited for?

Aquariums under roughly 20 litres — nano tanks, betta tanks, shrimp tanks, and desktop planted setups.

Do I need to prepare the diffuser before first use?

Yes — soak it in clean water for about 30 minutes so the ceramic disc is fully saturated before connecting CO₂.

How do I clean a clogged diffuser?

Soak the ceramic disc in a diluted bleach solution (about 1:10) for roughly 30 minutes, then rinse thoroughly before reuse.

Is this diffuser safe for shrimp?

Yes, when CO₂ is introduced gradually and monitored, this size is a popular choice for shrimp and nano tanks specifically because of its fine, controllable bubble output.

Can I use this with any CO₂ regulator?

Yes, it's compatible with standard CO₂ tubing and works with Chihiros regulators as well as most third-party CO₂ systems.
