 Topic: Tunze nanostream
Posted: February 08 2016 at 1:11am |

Just wanted to see what you guys thought about the tunze nanostream pumps, do they put out a good wide flow? Are they quiet? And most importantly are they reliable? I had my jebao wp-10 go out on me and was thinking of picking up a tunze but really haven't heard much about these pumps, thanks for the help!

The design does not make sense to me, efficiency-wise. The water is redirected at once as it comes off the propeller, wasting flow energy right out of the gate.
The best stream pump for the money is the Maxijet. Looking at gph/$ the Maxijet is 200% better than it's nearest competitor - not opinion, just fact. If placed down low shooting up, the pump can be partially hidden behind a rock, making the display more aesthetically pleasing and the water efficiently oxygenated. *
Aloha, Mark 
* gph is meaningless if the water is not efficiently oxygenated and waste not removed from our sessile invertebrates via properly directed flow.

I would replace it with a Jabao RW-4 or maybe a pair of them. I've been running 3 of them for over a year without any issues and they move a lot of water.
While I agree that the Maxijet is a good utility pump I have to disagree on some of Mark's points. The last time I was in the ocean I never found a place where there was a jet of water blowing at me at a constant rate and constant direction. I instead found larger currents moving in many directions and changing intensity. While I agree that we need lots of flow in our systems to help oxygenate as well as remove waste, I find moving a large quantity of water in random currents to be much more efficient at accomplishing this than just a jet of water pointed toward the surface only.
I hope that helps.

I thought about doing the Tunze myself but in the end I plan on getting the Jabao RW-8 for my 60 Gallon cube. I've just heard lot's of good things about it, also has been recommened by many friends, also for its price point and what it can do it's way nice!

do you think an RW-4 would be to much for a 24 cube?

One rw-4 in a 24 cube should be good. I don't think you will be able to run it at 100% but they are controllable. A lot of it also depends on the placement in the system.

I would think you'd be fine you'll just have to run it at a lower setting. But if your just doing easy corals like Mushrooms and Soft, etc that don't need as much flow it might be to much. From what I have read they are way powerful. I might personally do a Hydor Koralia Nano 565gpa on that size of tank. Then again love the controls on the Jebao. Here is a link to a form talking about the Jebao. There is a guy that posted on it and he has a tank close to yours. http://utahreefs.com/forum/forum_posts.asp?TID=79001&title=jebao-rw4-or-rw8

Sorry to disagree, but there are places like that. It may surprise you to know that coral grows like "krazie"  in those areas too. The speed of water flow around coral is measured in feet/second. It has been found to be something that we could never hope to duplicate in our aquariums. To make up for this inability, we do many things, one of which is to keep parameters like Alk, Ca and Mg elevated above natural levels in the ocean.

Have you read The Captive Reef by Dana Riddle? Dana did some great work in describing many distinct environments in which different general classifications of coral are found. He analyzed about 10 different places, such as the reef front, back, face, slope, channels, etc. He described both light intensity-spectrum and water movement in those environs. He wrote about turbulence, laminar flow, random flow and more. Though I somewhat agree with Krazie, Dana's conclusions about water movement on the reef and how to translate that information for our "captive reefs" will surely surprise you.
Again to quote Krazie, "currents moving in many directions and changing intensity". This is also called turbulence. The pics below show surface wave action. This is only a hint at the serious turbulence caused by a 1300 gph powerhead aimed vertically upward in 40 gal breeder tanks
Aloha, Mark

Why translate when we can now mimic what happens in nature? We may have needed to translate in the past when we didn't have controllable devices that can almost exactly duplicate tides and current surges, I don't think that is any longer the case.

I'm using a RW-4 in my 29 gallon bio-cube. It does a good job and I like that I can control and change speed and duration of the on/off times. I think it would work well in a 24.
Good luck.

Don't get me wrong. I'm not saying not to use the new technology which has greatly improved reefkeeping. What I am saying is that it can be done efficiently on a small budget. I believe there are many hobbyists reading this, perhaps more than we know, that want a nice tank, but they want it to be affordable for them.
Dana found that strong laminar flow was generally just as good as strong turbulent flow. Remember too, many coral (soft and LPS) do not do well when the flow is too strong. They don't like to be blasted.

what setting and speed are you running yours on? also how is it positioned in your tank? any sand dunes lol?

Speed: all but one light showing Mode: W1 Dial: set about 11 o'clock
The RW-4 is placed in the upper right-hand rear corner, facing towards the opposite, left-hand front corner.
No sand dunes ... but my tank is heavily stocked.
I also have a small Hydor Koralia placed low in the rear center, behind the rock, facing directly straight forward. My return is upper left hand corner, aimed at the front, center of the tank.
I've actually been considering adding a second RW-4 because I'd like to play with the sync function!
I'm of the opinion that you can't really have too much of the right kind of water movement.

Sounds good Shane thanks for the info, I guess I'll order a RW-4 pretty soon let's hope it lasts

Just added 2 RW8 to my 90 from the WP40 the controllability is amazing, I accidentally sloshed water out on W1 using the wireless with master and slave. Polyp extension is better, I'm looking forward to this change. I still use a wp10 blowing across the bottom of my tank behind the rock.

Nice, where did you pick your RW-8's up at?

I have a RW-4 too but obviously don't know how to run it... is there an online guide for this thing?
