Large Tank in Germany

[Claudio D]

Thanks again Wolfgang

So I understand that all the piping you installed in your tank was later removed?? and now you have an Open flow to the front glass that by turbulence moves every thing??

The programming is done in the frequency control or is by another device?

Have you tried "pulsing " the flow in order to produce a more natural oscillating movement?

I know I asking to much but I really like your solution, my tank is 1600 lts, (2200 lts the whole system)and I started with Ocean Motion and a very powerful pump and I had to removed to much maintenance, and finally the OM blocked itself, now I am installing some tunzes but I am not completely happy yet, And this next project I will assisting will be "bigger" (3mts by 1,2 mt (1,5 tops)) the front pane and we have nod decided how wide will it be (may be 1,2 mts or 1,5 tops). So circulation is a bigg issue

The Idea is a Caribbean Reef (I live in Venezuela) ( I know is not going to be so colorful but will have many interesting species), but the idea is to showcase local fauna

any way thanks you again for your patience, I am not sure if we can discus costs on the open forum, for that I will PM when we get closer to the decision making

regards

Claudio

Hi Claudio,

yes, I removed the piping, the open flow is sufficient and produces a rather smooth laminar flow. With the pipe construction the stream was to selective and to strong.

You will see the outlet only if you know where it is:

I have done the programming by using Siemens LOGO, but any device / wave controller that produces 0-10 V will be suitable. If you like to use Siemens LOGO I can provide the solution to you.

Pulsing is possible. In my tank I can produce a 2 cm wave without a wavebox, just with pulsing. If you mount the pump horizontal you can also use the direction change combined with pulsing.

In my tank I have three different programms, depending on the weekday. So there is good and bad weather.

I combine ramp profiles of different strength, overlayed with pulsing, displaced by calm periods and storms.

Compared to tunze: you can not compare it.

Are you still using 20000k bulbs for your 400watt lamps or did you switch them.

Was the propeller pump produces by Torsten at Korallenwelt. I've seen him using one on his web page.

 

[wolfgangcolsman]

Meanwhile I use 20000 at the rear, 14000 at the front.

The propeller was produced by a manufacturer that produces bow thrusters for many years. Torsten made one for his own.

Hi Wolfgang

Many thanks again

I a using AquaCOntroler in order to control my tunzes, I understand that Tunzes are 12/24V

LOGO is a PLC? I am not familiar with it

Hi Claudio,

LOGO is a small programmable controller having a graphical programming environment.

If your controller does have more then 10 V you can use a voltage devider (just two simple resistors) , that should not be a problem.

But are you sure that tunze uses 12 V for the control lines?

 

[Claudio D]

Wolfgang

To be honest I do not know if is it 12 or 24V, I should check, I know is it DC low voltage

Any way I can also contact the Neptune Systems to find out how they control the TUNZES

Thanks again I will keep you posted

regards

Claudio

Hi Claudio,

the manufacturer usually produces bow thrusters. He developed that one according to my specifications.

Since I got some more requests I think about making it available to the market.

For public aquaria, where noises are not a problem, it would be possible to double the power by changing the design of the electromagnetic coils.

Finally, I reduced the piping to a 67° angle that blows down to the front. With this design I really have almost no dead places without current using just one pump.

In order to reduce noises I changed the fixing to EPDM buffers (the vertical pipes contain casted lead to hold the pump down):

Normal operation is 50.000 to 100.000 l/h (at a 8.000 l gross volume). At this speed it produces almost zero noises,

Every hour I increase the outcome to 200.000 l/h for 30 secs, that raises all detritus in the system to make it available to the corals.

Once a day I raise it for 30 min to make the detritus available to the skimmer.

After 9 month of operation it still does not have to be cleaned. It has just a thin layer of bacteria and small sponges on the case.

The screen that you have in the picture is that the in take?

Also I noticed you remove all the piping on the output. Don't you get more direct flow the way it is now, as with before you get more indirect flow due to several output pipes directing flow?

Thanks

Kevin

Hi Kevin,

yes, the screen in the in take. It is covered my 3 overlapping layers of decoration material that hide it but provide enogh space to let the water pass.

Yes, I removed the piping. The flow now is more indirect now, because the water is distributed by the front glass

Hi everybody,

Peter made a new video. The tank is running 11 month now:

Stunning! What are you goals as far as fish population? It seems you have stuck with large groups of more peaceful anthias/basslets and some small groups of some of the more passive tangs. Any plans on adding in anything bigger (I saw the batfish, very nice) like triggers or angels?

 

[PerezAF01]

Nice Tank

 

[wolfgangcolsman]

Hi,

since I have a couple of sponges and many LPS I am not sure about triggers and angels. Any recommendation?

 

[kinlayan]

If you want triggers for your Aquarium, you cant beat the crosshatch trigger for beauty and quite reefsafe to a degree

Beautiful Aquarium, i love the decor and the fish selection!

Hi Wolfgang. Ihr Aquarium ist schön!
So natural and interesting...

What is the fish at 1:55 in the video?

 

[wolfgangcolsman]

Hi Mike,

the fish at 1:55 ist Serranus tortugarum, very easy to keep in groups, I have about 20 of them in the tank.

The tank is 2,3 x 1,8 x 1,8 m.

I just figured out how to use google translate, so here is the link to the tank setup translated to english (at least it looks like :reading: )

[skanderson]

thanks for posting all you have over here on this forum. i love the tank esp the deep dimension. ive been reading the translation of your german site. best part is it keeps translating something, im assuming tank, into pelvis. keeps me smiling when reading, and guessing every now and then as well. again thanks for keeping us informed, i am considering a project of similar scale to yours and am very interested in how you cutting edge ideas hold up after a couple years. i think the intank thruster/pump you have may be the way to go for flow in big tanks and am hoping it becomes available over here.
