Diffuser pressurized CO2 with bubble counter Sera Flore (model SE-08056)

Diffuser pressurized CO2 with bubble counter Sera Flore (model SE-08056) is a compact in-tank diffuser created for planted aquariums. It disperses pressurised carbon dioxide into the water column through a fine ceramic or similar porous element while an integrated bubble counter allows visual monitoring of CO2 dosing. The device is intended for use with an external pressurised CO2 system and is suitable for small to medium-sized aquaria where controlled CO2 supply supports healthy aquatic plant growth and stable water chemistry.

Advantages

The Sera Flore diffuser combines a fine-diffusion element with an integrated bubble counter to provide controlled and visible CO2 dosing without adding electronic components. Its compact design is made to be mounted inside the aquarium and offers consistent bubble production for easier rate adjustments. The diffuser materials are chosen to withstand continuous exposure to aquarium water and facilitate maintenance and cleaning when required.

Suitable for

• Planted freshwater aquariums with small to medium volume
• Hobby aquarists who require visual bubble monitoring for CO2 dosing
• Setups using pressurised CO2 regulators, valves and tubing
• Systems where passive in-tank diffusion is preferred over inline reactors

Key specifications

• Compact in-tank diffuser with integrated bubble counter for visual dosing control
• Fine porous diffusion element for efficient CO2 dispersion
• Designed for use with external pressurised CO2 systems and aquarium tubing
• Suitable for small to medium aquaria; internal mounting
• Materials compatible with continuous aquarium use and routine cleaning

How to use

Install the diffuser inside the aquarium at a location with moderate water flow to enhance CO2 dispersion. Connect the diffuser to the pressurised CO2 line using appropriate aquarium tubing and a shut-off valve or check valve as required by your CO2 system. Adjust the CO2 flow while observing the integrated bubble counter to set the desired bubble rate. Periodically inspect the diffusion element and clean or replace it if buildup reduces performance; follow standard aquarium maintenance practices when removing and handling the unit.

Usage recommendations

Position the diffuser where gentle circulation carries CO2 across the planted area rather than directly against filters or strong flow. Monitor plant response, pH and CO2 bubble rate together to maintain stable conditions. Regular visual checks and occasional cleaning of the porous element will help ensure consistent performance.
