SHIRUBA PRO series silent air pumps for nano to large tanks
The PRO series spans the PRO 2000 for small tanks up to the PRO 9000 for larger systems, so you can match output to your setup instead of overpowering a nano or starving a big tank. The single-outlet PRO 2000 is non-adjustable and quietly efficient for a desktop tank, while the double-outlet PRO 6000 and PRO 9000 add multi-stage flow control for running several sponge filters at once. All are built around silent operation, which matters in a home setting.
In Singapore’s warm 27-29C water, dissolved oxygen runs lower and bioload pushes harder, so steady aeration earns its keep even on planted tanks where surface movement helps gas exchange overnight. We suggest sizing up slightly if you plan to add tanks later, since a pump with adjustable outlets gives you room to grow. For bedroom or office use, the low noise here is a genuine advantage over older, rattly pumps.
