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”

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.

Product Questions

What size glass will this work with?
Question by: Anthony on Jul 30, 2023, 8:42 PM
Hey there,
Thank you for reaching out to us. This will work for glass up to 10mm.

Please let me know if you need anything further and take care!
Answer by: Matt Lucero (BRS Staff) on Aug 1, 2023, 8:20 AM
Will this work on a 120 gallon with a 30 gallon sump?
Question by: Brianna Long on Nov 3, 2017, 9:12 PM
Hey there,

These pumps are pretty low powered for that large of a tank. In most cases, reefers choose pumps that are in the 2500gph to 4500gph range for larger tanks like yours. :-)
Answer by: Randy on Nov 26, 2017, 10:06 AM
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 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!

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 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 on Dec 10, 2015, 3:01 PM
Do you need a separate controller to adjust the speed of the Tunze 6045?
Question by: Scott on Oct 4, 2013, 10:44 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.
