Quick Overview

Why does BRS recommend this?

Tunze Stream pumps are some of the quietest pumps for the price.  We have used these pumps in multiple tank builds and have never been disappointed.  They are not necessarily the cheapest AC powered pumps on the market, however they are very quiet, can be pointed in any direction, and have one of the industry’s best warranty and customer service through Tunze USA. 

German-made Tunze powerheads are one of the best high flow powerheads available. They are smaller and can be hidden in the aquarium easier than competing brands. Tunze pumps can be configured in a wide range of positions to target any area of the tank.

  • For aquariums from 10-55 gallons

  • Flow rate: 475 GPH

  • Energy consumption: 3.5W

  • Voltage/frequency: 120v

  • Cable length: 78.7”

  • Diameter: 2.7”

  • Output diameter 1.5/.59”


Full Details

Tunze pumps are excellent high flow powerheads for a number of reasons

  • They are the smallest pumps available and easy to hide.
  • They rotate to a wide range of angles for targeted flow.
  • They consume less power.
  • Available accessories such as the Tunze Rock and Controllers make them even more user-friendly.
  • Excellent warranty and customer service.


High flow is very important to maintaining a thriving healthy aquarium. Aquariums with poor flow can experience a number of easily avoidable health issue. Using high flow powerheads in your aquarium will:

  • Significantly decrease the risk of algae outbreaks.
  • Keep waste and particles suspended longer so skimmers and filters have a better chance of removing them.
  • Prevent toxic pockets from forming in hard to reach areas.
  • Keep debris from collecting on corals.
  • Keep food suspended longer so you can add less food.
  • Increase the chances of long term healthy tank success.

  • Compleatly silent and moves water well By Nicholas on 7/17/2017

    Can't beat the quality for the price , running 1 at the moment on a Nuvo 40 and will be geting a second to run on alternating times for random flow.
  • Good for ~40 gallons By Steve on 6/20/2017

    Purchased 2 of these for my mixed 40B reef. I put them side by side on one end of the tank next to each other to produce a gyre-like flow pattern. The flow wasn't as powerful as I expected, but it's more than enough for a mixed reef tank. Good product overall.
  • Excellent product for the price and the job By Roscoe's Reefs on 4/14/2017

    I have a 29 AIO and it needed more flow. Added two of these powerheads and am very happy. Thx
  • Great Power Head for $40 By Tom on 1/17/2017

    I use this Tunze 6015 to add flow behind my rock. For $40 it's easy on the budget and I like how easy it is to point in any direction. I really like how easy the Tunze design is to maintain. Just slip the ball out of the yoke and clean the power head. Everything else exactly where it is. It's much easier than removing the magnet and suction cup like you have to do with other powerheads.
  • Surprise Suprise By Adam on 12/14/2016

    I bought this to work in conjunction with my MP10, to help create more flow in my IM Lagoon 25. As I packaged this Tunze, I was surprised on its size. I was expecting it to be a little smaller in size, but was still happy with it since it is still smaller footprint then most. I set it up on the opposite side of the aquarium from the MP10 towards the rear of the aquarium to help create more flow behind the rockscape. Thats when I received my second when I applied power to it and noticed how powerful it was. I was able to position in such a way that it didn't stir up the sand since it is very adjustable and easy to position. Did also have slight issue with the rubber mounts at first, but after I pressed them in better it was fine and didn't pop out anymore.

    Bottom line is that this Tunze Nanostream 6015 may be slightly bigger than expected is still a great powerhead that packs some power. Easy to use and position with a great quality build at a low price point.
  • Nice gentle flow By Chris on 12/6/2016

    Using this in a small-fish QT tank (15 gallons) for quiet/gentle flow. Seems to be perfect for the application. Usual excellent Tunze quality.
  • Quality for a low price By John on 6/18/2016

    I got this pump just to mix salt water in a barrel and as a backup to have on hand. Well made and very quiet. My only complaint is that the little rubber mounts pop out really easily when moving the powerhead around. Not really an issue if it just sits in the tank in one place though.
  • Good product for a small tank By Eric on 3/31/2016

    Bought 2 of these for my 40B, didn't produce the flow I was expecting but should be more than enough for my tank. They're pretty quiet, just a small humm sound, overall would definitely recommend for the price and quality if you're looking for a nice compact powerhead!
  • Bigger than it appears. By John on 1/20/2016

    Bought 2 for my Red Sea Reefer 350 to create more turbulent flow with my Maxspect gyre. It is too big for my tank. I have ordered a different Tunze Nanostream and maybe that will work. Solidly built just not for me.
