For the fall the following new products will be available.

The Turbelle Stream is a high flow powerhead, the outlet is 2" indiameter creating a very wide flow pattern with no shearing forces. Two models to be available November of 2002.

The Bioelectronics (monitoring instruments) will be redone to feature a new soft touch key pad and a wall mount hanger. The monitors will retain the same premium lab grade glass platinum electrodes or carbon(conductivity) and reliable easy calibration features.

A new complete filter kit including sump, skimmer, bioreactor, mechanical filter, top off system and return pump designated Kit 16 will be available soon. It will handle aquaria up to 105 gallons and is expected to retail for under $800.

The Calcium Reactors have been redone to increase performance and efficiency. The new models will be available in October.

The Magnetic Rotor of the Turbelle Pump line has been upgraded to better resist the build up of lime deposits. The cooling passage is now twice the size and is designed to flush out deposits of lime. This is available as kit 3000.60 and is for all Turbelle pumps produced since 07/00.

Complete aquarium kits will be available soon, to view these and see a list of Tunze authorized dealers visit the web site at

I will let you know when they are available. I talked with Axel Tunze on Monday and it seems they were on schedule. I announce the date with some apprehension as demand is very high and I predict all of us will be fighting over who gets the pumps first. Not just here in the States either, at Interzoo their were people from the Middle East, all over Europe and the Orient offering to pay for 50-100 units in advance. When new products are released frequently the production is not as smooth as it should be, often the initial offerings are essentially hand made this might restrict supply but I will do everything I can to have them as soon as possible.

Hey Roger, good to see you as the Tunze Man in the USA. I am looking forward to the Tunze Stream pumps for a 750g tank in the next year or two. Can the larger Stream pumps be used on a wavemaker, like the multicontroller for the Turbelle's?

Finally, what is the most GPH that the Stream pumps will be able to provide? Any idea how big they are as well? I guess you have seen the Reeftec wavemakers here on Reef Central, they are a propeller based pump. Are these similar in design to the Tunze Stream pumps coming out soon?

Thanks for your help.

Hey Nanook,

If you use the link Roger provded, and go to the Interzoo section of Tunze's site you'll see an English PDF file that has the specifics of the stream at the very bottom. I think the PDF is called "innovations" and yes, the larger stream can be pulsed and is based on propellor technology though the design looks infinitely better than the "black box."
 
Thanks! I have read the site at Tunze, the pics were kind of small as well. I didn't see anything about their dimensions, unless I overlooked that?

sure, and that big one is going to be amazing at 3,170 GPH! I suspect, and obviously I could be wrong, that they'll be the same size as the current electonic powerhead. As I'm sure you know, they are all the same size in the current lineup and its likely that the same housing and motor is being used for the new one but just direct drive and a prop. Would make sense from a manufacturing standpoint. I zoomed that PDF pic to get a decent look at the pump and it does look very similar in size to the electronic powerhead. Can't wait to pick one up and I hope that Roger is able to secure some when they are first released.
 
The basic pump motor is the same size, overall the powerhead is slightly smaller as it lacks the strainer and flow deflector. It is magnetic drive, not direct drive.

Hey Roger, I just noticed this paragraph in your opening statement. Is this upgraded part for the "Classic" 2002 pump? I purchased my two 2002s about 6 months ago.
 
No, it is for the submersible pumps only, the 2002 and 4002 have had only a minor change of a seal added to the lower bearing to help prevent salt damage. I am unsure when this was implemented, yours are probably OK. I just noticed this addition when changing bearings for someone a few weeks ago.
 
Please don't blame MD they are new to the Tunze line and I think really are making a conscience effort to do a good job. I will get this cleared up tomorrow.
 
Hi Roger,

I have been following the thread with interest. I have been looking at Reeftec and Wave2k for an alternative to powerhead generated water movement. I am particularly interested in the Turbelle stream. I was looking a the website, and they listed a kit(TS24) that included two 6100 pumps and the 7094 multicontroller for $711.61MSRP and a single pump version with the single controller 7091 for $324.96MSRP. I only have a 50 gallon tank, so I am don't want to be blowing the animals all over the place. This is an issue of mine with the current Reeftec units. I like the back and forth effect that the Wave2k has but not the bulkiness of the unit. Would the single pump kit be sufficient for the type of water motion I want to have in my tank, or would the dual kit be better?

The information would be greatly appreciated.
Thanks in advance.

The output is 2" in diameter, the flow is diffuse. I still believe one would create more than enough flow in a 50gal. Fortunately being a low voltage electronic pump you will be able to turn the flow down as needed. To get a back and forth movement 2 would probably be best but start with one and by setting a high speed and a low speed you will probably get close to what you are looking for. While I know that the flow is diffuse and gentle even to a coral placed directly in front of the pump, I am unsure exactly how the pump will work in such a small tank. The display of the prototype was in an aquarium of about this size but it had no sand only various plates of glass to show that the great flow was not strong enough to blow them over. I expect these pumps to be available late Oct- early November.
 
calcium automat and kalk kit

calcium automat and kalk kit

any experience with the calcium automat unit? appears to be along the lines of a reactor for smaller tanks.

also the calcium despenser that works along with an auto topof unit. is that just essentially a kalk flowthrough?

thanks

The new Calcium Reactor 3174/3 is pretty nice. It works very well in conjunction with a Calcium Dispenser set. I have recently installed both on my 120 and I am still waiting for things to balance out but the pH is staying in a very narrow range already between 8.12 - 8.24. The Calcium Reactor has a small built in pump, the new design seals the pump to a stainless plate similar to how a Grolsch bottle closes. The water recirculates as does the CO2 which is free to rise to the top and is picked up by the recirculating venturi again. The new design also has two effluent drips and the manual suggests drip and bubble rate as well as how to use with the Calcium Dispenser based on aquarium size and inhabitants. It must be used with a pH controller. The Calcium Dispenser does essentially just mix up and dispense Kalkwasser- the advantage is it is a sealed vessicle so precipitate formation is unlikely, it is also very simple really nothing to break. My aquarium running the two systems for the 4th week now has a KH of 14 and Calcium level of 320ppm. Starting parameters were 9KH and 280 Calcium with a pH swing from 7.98 to 8.18 so it has definetly started to work but will require 3-4 months to really stabilize and show results. My aquarium is very diverse, the focal point is an 18" Yellow Ritteri, a 14" Gigas Clam, and a 12" Blue Derasa, I have numerous Acropora and Porites species and a few Lobos and Blastomussa as well as a couple of Leathers. The aquarium was recently torn down for a move, that is when I added the new hardware. Most of the animals have been maintained for 3-4years in the same aquarium but I became frustrated with using Kalk, Calcium Chloride and Buffer constantly and wanted to automate as well as clean up the plumbing and the entire Tunze Sump system. I also upgraded to Schedule 80 PVC and 45degree elbows while in the process of moving.
 
more questions

more questions

how much space does the reactor take up on a tank. i have rather limited space so its of concern. i really like the concept, and its reasonably priced. im thinking of getting the reactor setup, and running it manually untill i can afford the controler.

/john
 
Running it manually is likely to be a failure. This design is really dependent on the pH controller. I would recommend purchasing the reactor, the CO2 controller set and regulator all at once. You don't want to have excess CO2 in the aquarium or you will end up with algae problems. The pH is an important system feedback for KH and Co2 levels. This is really what regulates the reactor function. The unit is 4.5" square and 11" tall, 4" must be submerged. What size is your aquarium and what are the inhabitants, sump or no sump?
 
Hi Rvitko,

As most of the people here, Im very interested in the new Turbelle stream. Reading some of your post here, you mention that you saw one in action. Do you think that a cube tank of 38x38x38x24 will have enought water movement for SPS corals with two 6100 pumps and the 7094 multicontroller?. Im very interested; they look very nice and if with just two pumps I could get lots of courrents, will be great!; expensive but great.
Thanks
 
The Stream pump was demonstrated in an aquarium of 100cm in length (42"). The demonstration featured a pane of glass about 8" square on an equal size base. It was positioned about 12" infront of the pump to demonstrate that the extremely high flow was diffuse enough as too not move the glass pane. While in theory the total volume of two pumps would be sufficient and the pumps flow has a cubic spread i.e. at about 24" from the pump the current is about 24" wide and tall. I have some doubts as to whether this will be sufficient given the fairly extreme depth of the aquarium. I think my personal preforance would be, and this is bearing in mind your inhabitants and the fact that the diffuse flow will not carry as far as a more directed flow. I would use 2 7400/2 pumps positioned on the back wall. I would use extension tubes with T connectors and a second strainer to extend the intake from the pump positioned say 6" below the surface to about 1" above the substrate. This will sweep up settled detritus and bring the water to the surface for good gas exchange. This will also ensure good circulation behind the rock structure. To this I would add one Stream pump blowing across the rock structure, positioned on the side of the aquarium about 16" deep. This will require an extension rail. I would use the multicontroller such that it is in Tide mode, The 7400's would be on ports 1 and 3 and the Stream would be on port 2. This will set it such that the Stream will be on when the 7400's are off. While they are on I would set the power setting for 100% power and 50% power respectively with a 3sec cycle between settings. This will create colliding waves which will further broaden the flow. I would set the Tide program interval at about 30min but this is probably the variable that you will have to play with most. You can vary this setting between 1min and 12hrs. The photo cell will switch all pumps to 50% power or whatever your low power interval setting is. I think this set up will completely eliminate any dead spots. I am sure another configuration using Sea Swirls in place of the 7400's with a proper intake set up could work as well. I personnally like my sump to turn no more than 4X an hour as I use all Tunze equipment and excessive turbulence interferes with the skimmer, denitrators and osmolator. I have always gotten most of my flow through Turbelle pumps. My aquarium is a standard 48 x 24 x 24 120 and two 7400 pumps with a multicontroller and 500gph return provide sufficient flow for my diverse inhabitants including sps, lps,softies and a large ritteri with a few clams.
