Introduction
This manual provides instructions for the installation, operation, and maintenance of your Eheim Diffuser, designed for hoses with a diameter of 9/12 mm. This device is a venturi kit that facilitates the discharge of air into water, enhancing oxygen levels in your aquarium.
Product Overview
Image 1: Eheim Diffuser. This image displays the main components of the Eheim Diffuser, including the venturi body and air intake tube, ready for connection to an aquarium hose.
The Eheim Diffuser is engineered to enrich aquarium water with oxygen. It operates on the venturi principle, drawing in ambient air and mixing it with the water flow from your filter's outlet, then releasing fine air bubbles into the aquarium.
Setup Instructions
- Prepare the Hose: Ensure your aquarium filter's outlet hose has a diameter of 9/12 mm.
- Connect the Diffuser: Firmly attach the Eheim Diffuser to the end of the 9/12 mm outlet hose from your aquarium filter. Ensure a secure, leak-free connection.
- Position the Air Intake: Connect the small air intake tube to the designated port on the diffuser. Position the open end of this tube above the water surface, ensuring it can draw in air freely.
- Submerge the Diffuser: Place the diffuser assembly into the aquarium, ensuring the outlet is submerged and positioned to distribute oxygenated water effectively.
- Adjust Air Flow: If your diffuser includes an air flow adjustment valve, use it to regulate the amount of air drawn into the water flow. Start with a moderate setting and adjust as needed.
Note: Always ensure the air intake tube is clear of obstructions and positioned above the water level to prevent water from siphoning out of the aquarium.
Operating Instructions
Once properly installed, the Eheim Diffuser will automatically begin to draw air into the water flow from your filter. The venturi effect creates a vacuum that pulls air through the intake tube, mixing it with the water and releasing fine bubbles. This process significantly increases the dissolved oxygen content in your aquarium water, which is vital for the health of fish and beneficial bacteria.
- Continuous Operation: The diffuser is designed for continuous operation alongside your aquarium filter.
- Visual Check: Regularly observe the diffuser to ensure a steady stream of fine bubbles is being produced.
- Air Flow Adjustment: If equipped, use the air flow regulator to fine-tune the amount of air introduced. More bubbles generally mean more oxygenation, but excessive surface agitation can lead to CO2 loss in planted tanks.
Maintenance
Regular maintenance ensures optimal performance and longevity of your Eheim Diffuser.
- Weekly Check: Inspect the diffuser and air intake tube for any blockages, such as algae or debris.
- Cleaning the Diffuser:
- Disconnect the diffuser from the filter hose.
- Gently clean the diffuser body and the air intake nozzle using a soft brush or cotton swab to remove any accumulated grime or algae.
- For stubborn deposits, soak the diffuser in a mild aquarium-safe cleaning solution (e.g., diluted vinegar or a commercial aquarium cleaner) for a short period, then rinse thoroughly with clean water.
- Cleaning the Air Intake Tube: Ensure the air intake tube is clear. If it becomes clogged, use a thin brush or pipe cleaner to clear the obstruction.
- Reassembly: Reattach the cleaned diffuser to the filter hose and air intake tube, ensuring all connections are secure before returning it to the aquarium.
