Frequently asked questions

What aquarium size should the Nanostream 6040 fit?

It's tuned for 40-400 L (10-105 gal) — a larger tank would benefit from a Turbelle Stream model (unit flow is 1000-4500 L/h, double it for long aquascapes).

Is the Nanostream 6040 quiet?

Low-noise operation. The modern drive cell minimises vibration when the mount is properly seated.

How do I mount the Nanostream on my glass?

Uses the included Magnet Holder — for glass up to 15 mm thick. Point the outlet toward the opposite side of the tank to build a circular current.
