In modern aquaculture, proper aeration is the backbone of healthy and productive ponds and tanks. Whether you’re raising shrimp in biofloc systems or fish in Growout ponds, the type of aeration tube you use can make a big difference in water quality, oxygen transfer, and overall yield.
To help farmers make the best decisions, AirOxi has released its updated Air Flow Rate Reference Chart (Ver 2.1, July 2025). Here’s a breakdown of the key insights from this chart and how you can use it to improve your farm’s performance.
Why Aeration Matters
Efficient aeration ensures:
- Sufficient dissolved oxygen levels
- Uniform water movement
- Reduced sludge accumulation
- Improved feed conversion ratio (FCR)
But not all aeration tubes are made equal. Based on your blower type, pond design, and farming system (biofloc, nursery, RAS) — you need to select the tube that fits best.
AirOxi Tube Comparison: At a Glance
| Tube Type | Air Flow (m³/hr) | Best For | Blower Type | Oxygenation | Maintenance |
| AO125250 (Blue) | 2.0 | Growout, nursery | Root blower | High | Medium |
| AO125225 (Yellow) | 2.2 | Biofloc tanks | Ring blower | High | Low |
| AO-25 Star | 2.2 | Biofloc | Root + Ring | High | Low |
| AirOxi Pearl (AR) | 1.6 | RAS | Root blower | High | Medium |
| AO250380 (White) | 3.2 | Biofloc tanks | Root blower | High | Low |
| AirOxi NC-16 | 2.2 | Mud-bottom ponds | Ring blower | Low | Low |
| AirOxi 1020 | 1.4 | Small tanks | Air pump | Low | Low |
| AirOxi Spider (Design X & O) | 2.4 | Biofloc/fish tanks | Mixed | High | Medium |
| AirOxi KING Spider | 2.4 | Circulatory aeration | Mixed | High | Medium |
💡 Note: These are indicative values for 1 meter water head at 200 mbar pressure. Real-world performance may vary.
Matching the Right Tube to Your Blower
| Blower Type | Compatible Tubes |
| Root Blower | AO125250, Pearl, AO250380 |
| Ring Blower | AO125225, NC-16, Xtra |
| Root + Ring Combo | AO-25 Star, Spider series, AirOxi 19 |
| Air Pump | AirOxi 1020 only |
Maintenance & Lifespan Tips
- Algae Resistant (AR) Tubes like AO125250-AR & AO125225-AR are ideal for longer life and reduced clogging.
- Fine bubble tubes like AirOxi Pearl are excellent for oxygen transfer but require more care.
- Rough finish tubes like AirOxi Xtra are better for water movement but can accumulate debris faster. For more info please click this link https://airoxitube.blogspot.com/2024/04/which-airoxi-aeration-tube-is-suitable.html
Conclusion: Which One Should You Choose?
Choose your aeration solution based on:
- System Type (Biofloc, RAS, Nursery, etc.)
- Blower Availability
- Water Depth
- Desired oxygenation and water circulation
For example:
- For biofloc tanks, go with AO-25 Star or AirOxi Spider.
- For RAS systems, AirOxi Pearl is your best bet.
- For mud-bottom Growout ponds, choose AirOxi NC-16 for lower cost and ease.
