Product information
Description
🔹【Air Pump Power】Small, low-power air pumps are insufficient; a powerful pump is essential. The longer the tubing, the higher the required pump power. 35cm 3-ring model: recommended pump power 50–60 l/min (18–20 W), suitable for large aquariums and high-density breeding.
🔹【Bottom Stability】Equipped with an 8mm thick 304 stainless steel weighted ring, the diffuser remains firmly seated on the bottom without floating.
🔹【Standard Connection】The connection is a standard brass air hose fitting, with an 8mm inner diameter and a 10mm outer diameter, and connects directly to standard air pump outlets. Included: 5 meters of transparent PVC tubing (9/12mm).
🔹【Versatile Use】Suitable for home aquariums, koi ponds, ornamental ponds, garden ponds, biofilters (moving bed systems), still waters, and aquaculture systems.
Installation Instructions:
① Check the air pump
② Connect the tubing
③ Place the diffuser, avoiding burying it too deeply in the substrate
④ Turn on the air pump and test it
⑤ Install a check valve between the air pump and the tubing to prevent backflow and damage to the pump in case of a power outage (optional)
Common Problems and Solutions:
① Are the bubbles only partially emerging or are they coarse?
→ Insufficient air pump power, blocked micro-openings, kinked hose.
✅ Use a more powerful air pump; rinse with clean water in reverse through the air inlet or soak for 10 minutes in vinegar to dissolve limescale deposits, then rinse thoroughly.
② Is the diffuser floating or tilted?
→ Airflow too strong, placement on a loose substrate or in a depression.
✅ Gently press down on the diffuser; place it on a flat, hard surface; start the air pump at low power, then increase it once it stabilizes.
③ No bubbles form?
→ Defective air pump; kinked hose; incorrectly installed or blocked check valve.
✅ Disconnect the diffuser and immediately start the air pump to check if air is coming out.
Tips:
Before first use, rinse the diffuser inside and out with clean water to remove any manufacturing residue.
Never run it dry for extended periods, as this could damage the micro-openings.
With a suitable air pump and proper installation, this diffuser will operate stably and reliably.
