- 400 L/hr air output (as stated in title)
- Twin outlet design for running two lines or splitting airflow
- Suitable for aquariums, aquaponics, and hydro reservoir aeration (general use)
- Simple way to improve oxygen levels and water movement
Best for
- Medium to larger reservoirs/tanks needing dependable aeration
- Running two airstones or two separate air lines
- Aquariums, sumps, aquaponics systems and nutrient tanks
- Growers wanting steady dissolved oxygen support in water culture systems
How to use
Connect airline tubing to each outlet, add a check valve if needed, then run to your airstone(s) or air diffuser(s). Use an air control valve if you want to fine-tune airflow per line (general guidance).
- Use check valves if the pump sits below the waterline
- Keep the pump in a dry, ventilated location
- Match diffuser size to pump output for best performance (general guidance)
