Tunze presented a few goodies at Interzoo. Notably, the Nanostream now has a built-in flow controller, allowing for four different flow settings. As such, the 6045 will have a much wider application, which is great news for those who deemed them a little overkill for their smaller tanks.
Even better though, Tunze also launched the Masterstream line intended for much...larger applications. Apparently this thing can empty a bathtub in 1.8 seconds! Check out the specs on reefbuilders.com.
