Clscea Acrylic Aquarium CO2 Diffuser, Large with Bubble Counter and Replaceable Ceramic Plate

Clscea Acrylic CO2 Diffuser is made for supplying CO2 to planted aquariums, with an integrated bubble counter and a replaceable ceramic plate.

• Transparent acrylic body — offers a glass-like appearance in a material described as more durable than glass and not fragile.
• Integrated bubble-counter cup — add water to the cup to track bubbles as they pass through.
• For pressurized CO2 systems — requires at least 1kg/cm² (14PSI) working pressure for optimal operation.
• Injection-molded ceramic plate — its effective outlet area is 1/3 larger than that of similar products, supporting higher CO2 dissolution rates.
• Replaceable ceramic plate and a Clscea warranty — provides a replaceable diffuser component and manufacturer warranty coverage.
• Fits 4/6mm (3/16" inner diameter) CO2 tubing — matches the stated tubing size for connection to a compatible setup.

Delivering CO2 through a diffuser is part of a pressurized aquarium setup for planted tanks. This model combines the diffuser and a bubble-counting cup in one unit, so the bubbles can be observed at the device while CO2 is supplied. Its specified pressure and tubing fit help determine whether it suits the existing equipment.

What pressure does this diffuser need?

Clscea Acrylic CO2 Diffuser needs at least 1kg/cm² (14PSI) of working pressure for optimal operation, so it is intended for a pressurized CO2 supply rather than an unpressurized source. The ceramic plate is designed to seal effectively and help avoid large bubbles; the larger effective outlet area is intended to support higher CO2 dissolution rates.

• Made for pressurized CO2 supply systems.
• The ceramic plate is injection-molded and replaceable.

How does the built-in bubble counter work?

Add water to the integrated cup and it becomes a bubble recorder, making bubbles visible as CO2 passes through the diffuser. This gives aquarium keepers a built-in way to observe bubble activity without a separate bubble counter.

• The water-filled cup serves as the bubble-counting chamber.
• The counter is incorporated into the diffuser body.

Which CO2 tubing does it fit, and how should it be cleaned?

Clscea Acrylic CO2 Diffuser fits 4/6mm (3/16" inner diameter) CO2 tubing. Compare that tubing size with your setup before connecting it. For care, do not use alcohol to clean the diffuser, because alcohol can damage the acrylic.

• Designed for the stated CO2 tubing size.
• Avoid alcohol during cleaning to protect the acrylic body.

This diffuser is suited to aquarium keepers using a pressurized CO2 system with compatible tubing who want an integrated bubble counter and a replaceable ceramic plate. Its pressure requirement, tubing fit, and alcohol-related care restriction make the key setup and maintenance considerations clear.
