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.

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

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.

Drive shaft has issues only after short period of time By John on 12/28/2019John wouldn't recommend this product to a friendI have had fish for over 30 years and have used a number of powerheads. I previously used the Tunze nano 6045 for 3 years and it awesome. For my 350 gallon build, I included 5 Tunze 6125 powerheads. The directional capabilities are really good and do move a lot of water. My issue is that after 2 months, pump #4 got stuck on after my daily feeding in which all powerheads are off. Scared that daylights out of me as it sounded like something was being electrocuted. Shutting off the powerhead and restarting it allowed it to work. It happened again in a few days. It gradually increased until it happened every time (took 3 weeks). Cleaning it didn't help. Customer service was great, but it took a long time to convince them it was not due to non-maintenance or constant starting or stopping (no wave maker, only oncea day at feeding). Finally I realized that the propeller on the drive shaft moved away from the magnetic end of the shaft, did a 1/8 of turn, and got stuck on the notch on the shaft. If I put it back it place, it worked fine for a week or so, then started the above issue over. Tunze did sent me 2 new drive shafts, but out of the 5 units 2 had the above problem and 1 does it occasionally. The other issue I found is that removing and then later reassembling the cage to get at the drive shaft is really hard to do. Very frustrating. Good Company, just the impeller on this product is a dud.
A bit big, but awesome directional flow By Jay on 8/4/2018Jay would recommend this product to a friendI've been using Tunze powerheads for several years now and got the Turbelle Stream 6125 for my 150 gallon fowlr tank. The 6125 itself is a bit big in size, but it blends well with my blackground and really isn't even noticeable in the tank. The flow is awesome and reaches all the way across the 5-foot length of my tank in a generally wide pattern. I have the 6125 flowing into a random flow generator return nozzle and this creates nice random flow within the tank. Also, I think the ability to point the Tunze's flow in any desired direction makes these superior to most other competitors. Plus the 6125 and all other Tunzes I have have been quiet and super reliable. I give the 6125 4stars really only because of the size, but I am very very happy and satisfied with this Tunze product and may add 1 or 2 Tunzes to this tank in the future.
The best pump I have ever bought! By Brandon W on 9/29/2012Brandon W would recommend this product to a friendThis powerhead is def worht the $$ becasue It blows krollia out of the water by far, but don't get me wrong they are nice. This pump is very quiet and I have it in my 90 mixed reef and I have no need to adjust where I want my flow do to the new nozzel wide spread flow. it gets the front just as good as the front all away around. personally I think just this pump alown would be fine for mixed reef, but since I like to go to the extream I like to add a little more flow, but I went Tunze all the way.!!!!
