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.

Wanted to try this pump in my 40gal and it has good flow. I will be getting one more for good cross flow.

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.

Tunze makes great products. The flow adjustment is nice. The 6045 really moves some water compared to its size.

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.
