Which air pump do I need?
Pick your system, enter how much water is in each bucket or reservoir, and we'll suggest an Aqua One pump.

Each bucket gets its own air line, so the pump needs enough outlets.
Quick sizing table
| Pump | Outlets | DWC (per bucket) | NFT / Ebb (per res.) |
|---|---|---|---|
| Aqua One 2500 | 1 × 160 L/hr | 1 bucket up to 40 L | 1 up to 80 L |
| Aqua One 7500 | 2 × 180 L/hr | 2 buckets up to 45 L or 1 up to 90 L |
2 up to 90 L |
| Aqua One 9500 | 2 × 200 L/hr | 2 buckets up to 50 L or 1 up to 100 L |
2 up to 100 L |
| Aqua One 12000 | 4 × 200 L/hr | 4 buckets up to 50 L or 2 up to 100 L |
4 up to 100 L |
This is a guide, not a rule. Water temperature (warmer water holds less oxygen), bucket depth, air stone size, tubing length and plant size all make a difference. If you're between sizes, or your water runs warm in summer, go one size up.
