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 10-135 gallons

  • Flow rate: 400-1175 GPH

  • Manual Flow Adjustor

  • Energy consumption: 5 to 7W

  • Cable length: 78.7"”

  • Diameter: 2.75”

  • Output diameter 1.5/.59”

Manufacturer's Manual

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 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.

  • Lower then expected life By Daniel on 4/17/2017

    1.5 years after purchasing this power head the tabs on the end of the nozzle that stop the impeller from spinning backwards have broken. Now the impeller seems to always spin backward when it starts unless I play with it
  • Great By BNF27 on 4/6/2017

    the product performs as stated
  • Quiet and powerful By Chris on 12/6/2016

    After trying many techniques and products for providing circulation in a reef tank over the years I have come to prefer Tunze powerheads for their simplicity, build quality, longevity, ease of maintenance and energy efficiency. Worth the extra bucks IMO.

    I'm using a couple of these (and a 6025) in a small reef (65 gallon). Great design, easy to install/aim. They provide nice strong flow without blowing the sand around or beating up the anemone. No audible noise...the usual excellent Tunze quality.
  • Cheap quality fish guard. By Andrew on 9/27/2016

    I ordered two of these for my 75g reef build. The pump quality seems nice other than the fish guard, the reason for only 4 stars. The pumps are very small and versatile with aiming angles. When I received my pumps both of the fish guards were broken. BRS has amazing customer service and sent me two new pumps and upon inspection one of the two new pumps also has a broken fish guard. That's my only complaint.
  • Failed after 1 month of use. By jeremiah on 3/16/2016

    I am new to the hobby and have started a 60 gal reef tank. I purchased this unit less than a month ago and it has already failed. I am going to contact BRS on what i can do to return the product. It was recommended by BRS so i trusted the recommendation. The unit has a very small design and i like the adjustments that can be made directionally for this pump. I am considering asking for credit to purchase some dc versions that have the cords outside tank.
  • Nice pump By Curtis on 4/26/2014

    Wanted to try this pump in my 40gal and it has good flow. I will be getting one more for good cross flow.
  • good water movement By Kris on 3/18/2014

    I do like these powerheads, i ordered 2 for my 65 G mixed reef. They move a lot of water and are quite small. The magnets barely make it through my glass (1/2") but they do hold OK. The flow is a bit narrower than I thought. I initially bought the sicce voyagers but replaced them with these, and am much happier with the Tunze ones.
  • great little wavemaker By RWL on 7/30/2013

    installed 2 in a 75 gal. unobtrusive, very quiet, works perfect, manual adjustment works great, easy to adjust direction.
  • great product By John on 4/13/2013

    Tunze makes great products. The flow adjustment is nice. The 6045 really moves some water compared to its size.
  • great powerhead By 241wrasse on 12/22/2012

    Bought a 6045 about 3 months ago, & was certainly impressed! Design, size, overall quality beat the pants off my older existing Hydor Koralias. Absolutely love the ball design of the impeller cage - truly does let you swivel the head around in any direction you want. Small size = less obtrusive. Excellent Tunze qualtiy, very quiet - even on startup, not like the big grinding/rattling noise the Koralias make when they start up, & yes the Koralias are well-maintained.
  • vibrates more than earlier versions By Frank on 11/22/2012

    Disappointed with this version. I own an earlier version that does not have the "flow adjustment" and was extremely satisfied with its performance, which is why I decided to buy another one. This version vibrates like mad and I had to adjust the flow setting to minimum to avoid the noise that it was creating, which I believe was caused by the impeller blades hitting the housing of the flow adjustment tube. Additionally, the vibration is significantly greater than the older model. Given the price, I expected better performance and now I have to look for another one.
  • Looks great and work even better!!! By A. grandis on 11/8/2012

    I've got my 4th nanostream 6045 for my 75gal zoa tank and it's just amazing.
    The only thing they changed was the magnet. There is one small and one bigger, instead 2 small magnets. I contacted Tunze and they said they needed to change the mags in order to keep the prices in a good range. Tunze says that the new mag can go in the water and won't rust, even without the protection the smaller has. Not a big deal!!
    Very good quality and efficiency.

Product Questions

Would this pump be suitable for a 60 gallon 24x24 inch cube? LPS only right now. If not, can you recommend a good pump under $100? Thanks.
Question by: Derrick on May 31, 2017 2:01:00 AM
Tunze pumps are among the best, and depending on the desired flow for your tank, such as a more low to moderate energy tank such as yours, this pump should do very well.

Happy reefing!
Answer by: Zack (Admin) on Jun 7, 2017 3:52:00 PM
If I get the 6054 and the Tunze to APEX cable, do I need to get anything else? I plan to get the 6054 without a controller and use my apex to control it. Does it need separate power to drive the powerhead?
Question by: Thomas Li on Dec 5, 2015 1:40:00 PM
Great question!
The 6054 is not a controllable pump and does not come with the option to hook up to the apex besides by plugging it into an outlet which can turn it on or off. You will need to select a tunze pump with a controller pictured for control through an apex on speed and other things. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Dec 10, 2015 3:01:00 PM
Do you need a separate controller to adjust the speed of the Tunze 6045?
Question by: Scott on Oct 4, 2013 10:44:00 AM
Hi Scott,
The 6045 isn't electronically controllable so you do not. It has a slider on the side of the pump that you manually adjust to change the flow.
