Clscea External Inline CO2 Diffuser, 16/22 mm Hose, DC400-L-16 with Bubble Counter

Clscea External Inline CO2 Diffuser Atomizer is made to add CO2 to a planted aquarium through a canister-filter setup, with 16/22 mm hose compatibility and an integrated bubble counter.

• External inline installation — keeps the diffuser outside the aquarium and leaves tank space free.
• Open-flow design — does not limit filter flow.
• 16/22 mm hose fit — made for hose with a 16 mm (0.63 in) inner diameter.
• Horizontal or vertical connections — lets you choose the connection direction for your setup.
• Integrated bubble counter and check valve — monitors bubbles and helps prevent water backflow.
• Designed for efficient CO2 dissolution — the manufacturer says its design dissolves CO2 more efficiently and saves CO2 compared with in-tank diffusers.

Adding CO2 to a planted aquarium can involve equipment inside the tank as well as filter plumbing. This aluminum alloy inline atomizer places the diffuser outside the aquarium and connects it to a canister-filter hose, keeping the equipment arrangement compact inside the tank. Its visible window also lets you see the diffuser at work.

Will the Clscea inline diffuser fit my filter hose?

It fits 16/22 mm hose with a 16 mm (0.63 in) inner diameter and is intended for use with a filter. The two connection orientations accommodate either a horizontal or vertical arrangement, so you can select the direction that suits your filter plumbing.

• Product model: DC400-L-16.
• Use with a filter; the diffuser is not a standalone aquarium device.

How does the Clscea diffuser connect and work?

The diffuser connects inline outside the aquarium and is designed to dissolve CO2 in the filter flow. Its 100% open-flow design is made not to restrict that flow, while the manufacturer’s stated efficiency comparison is against in-tank CO2 diffusers.

• The transparent window provides a view of the diffuser’s operation.
• The bubble counter includes a built-in check-valve pad to help stop water from flowing backward.
• The built-in valve means a separate check valve is not required.

What can I maintain on the Clscea diffuser?

The diffuser includes a bubble counter, and its diffuser disk can be removed for cleaning or replacement. These serviceable parts let you access the disk for upkeep without changing the inline placement of the unit.

• Aluminum alloy diffuser body.
• Removable diffuser disk.
• Bubble counter included.

This model suits planted-aquarium owners using a canister filter with compatible 16/22 mm hose who want CO2 diffusion outside the tank. Its hose fit, filter connection, and external inline design make it a fit for setups where keeping equipment out of the aquarium matters.
