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.

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 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.

  • Not the Cheapest but not the most expensive either By Stephen on 5/15/2017

    There are cheaper products and there are more expensive products but if you are in for no frills product that built with quality then this is the product. There are piratically silent in operation. the only thing i don't like is the 4 blue stud things that the the power head mounts on to. these have a habit of coming out if you need to move the power head. Some of these float come don't but in either case you are playing hunt the blue widget all over the tank. I'm already thinking about getting some others and are certainly better value than the cheap Chinese knockoffs.
  • power head By dalbert on 3/17/2017

    didnt work for me lasted less then a month put a little more money in one and buy a good one
  • Good job By Good on 2/1/2017

    They do good job at ... how do you say ... moving water around.
  • Great so far but havent had for long By Keith on 12/5/2016

    I would like to start by saying I have only had this for about a month so I can't speak for the longevity of this pump. However, so far everything seems great! It is very quiet, the magnet easily holds it in my 3/8" thick glass and it is much smaller than my hydor koralia I have so it's not sticking out as far in the aquarium. In my short experience with this pump everything has gone very well.
  • good powerhead By R3 on 10/6/2016

    works well. does the job and helps give a full flow of water.
  • Great powerhead By Greg on 6/13/2016

    Quiet, great flow, compact and the clips won't break like some have said in other reviews. Just have to handle with care.
  • Works Great By James on 2/21/2016

    I bought 3 of these for my 75g tank, and they work fantastically. I will probably add another in the near future. Easy to clean.
  • Excellent Powerhead By Adadwa on 1/6/2016

    Very quiet and efficient. I have 2 connected to a wave maker and they are dead silent, no clicks at startup. Excellent water movement.
  • Outstanding Powerhead By Ronald on 2/20/2015

    This is my first Tunze product and I am extremely satisfied. Quiet operation and outstanding flow. Great compact powerhead, fits well in a biocube.
  • Moves water By Xavi on 2/26/2014

    This thing moves some serious water. I will be swapping out my other powerhead for another Tunze.
  • Good Powerhead Overall By Kyle on 2/21/2014

    First time buyer of Tunze. The flow is wide and gentle. The operate completely silent. They do have a small click sound on startup as someone else mentioned but it isn't a problem to me since they run 24/7.

    The build quality seems good and I think they will last more than long enough with normal maintenance. My only complaint about these powerheads is that the magnet is weak. I have a rimless tank so the glass is thicker. I have these on 1/2in thick glass and they would not stay supported unless the cord was somewhat holding it up. I remember moving the cord once or twice while setting up the tank with prior to filling with water and they would crash down to the bottom of the tank. If the magnet were stronger, it would get 5 stars as the silence is golden.
  • Upgrading from Hydor to Tunze Terbelle pump By ShadowACE on 6/26/2013

    Installation was a snap. A little more assembly than the Koralia.

    Too soon to tell on the longevity. but being German made I expect it to be better in the long run.

Product Questions

can I programs this pump with my apex for on and off wave maker scenarios ?
will it hold up?
Question by: vincent on May 10, 2016 6:13:00 PM
Great question! These pumps can be set up on the Neptune energy bar to turn on/off, and they certainly will hold up to this function, however, on/off action will shorten the life span of any pump you choose to set up this way.
Answer by: Carter (Admin) on May 10, 2016 6:44:00 PM
What size power head would you suggest for a 18 gallon nano reef? I will be placing different types of coral in it. There are so many options I don't want to get more than what I need and will I need to get more than one to keep down dead spots? The aquarium footprint is 16” x 16” x 17” for a total of 18 gallons.
Question by: Craig Watkins on Mar 9, 2016 6:05:00 PM
Great question!
Anything around 180-250 would work well and on a tank of that size you will not need multiple. You can get standard powerheads such as the Hydor Koralia listed below or DC controlable options Such as the Tunze Turbelle 6040. Feel free to let us know if you have any further questions!

Can I add the Tunze wave control system to this style pump? If so what components do I need?

Thanks!

Question by: Justin Fisher on Jan 8, 2017 5:31:00 PM
Great question! Unfortunately, the Tunze 6025 is not controllable and will not work with any Tunze Multicontroller. :-(
