6000 Stream has arrived

my concern

my concern

Many acrylic manufactures state that if you make any cuts or alter there tank the warranty is void.

Yeah, mine said that too but it had an integral internal overflow installe but no holes drilled in the bottom. How's that supposed to work. I think as long as you don't go crazy drilling holes everywhere you will be ok. I could see you having problems if you cut the entire top off but otherwise I wouldn't worry too much. If a tank is going to fail it will most likely fail when first filled. (Assuming its a new tank) For peace of mind you could fill it first with tap-water and let it sit for a few days. As a general engineering principal things are supposed to be overbuilt by 5-10X. For example, if some tubing is rated for 100psi it should be able to handle 500-1000psi for a brief period of time without exploding.

I forgot to add that stress is usually created at sharp angles. By drilling a hole you minimize the chance of a crack forming as opposed to if you cut a square out.

Photoberry,

I have an acrylic tank that has 2 rectangular holes in the back (I had them made for seaswirls). The holes are 5" wide, 1.5" deep and an inch from the back.

Since you already have a stream hooked up do you think this would work to hold the bracket and do you recommend the stream face the front of the tank? Or can I swivel the stream.

Thanks for all your help

 

[photobarry]

That would work great! You can easily swivel the stream so it can easily be pointed in any direction you want. I don't think you would want it facing the front of the tank. Its output is a very wide area of flow and works best when aimed at the opposite front corner of the tank. I believe this is what Roger normally recommends. It all comes down to where you want the flow in your tank.

Now I am liking this even more. If I have the stream right in front of me how many deggrees can I swivel it to the right or left. Aprox?

 

[photobarry]

90 degress either way.

 

[Mexican Hermit]

Cool,

How do I tell my wife about a $200 toy?

Would you recommend 2? with the multicontrol?

 

[photobarry]

2 would be great (with multicontroller) for a 4' long tank. Get ready to increase that $200 amount. Tell her its either the Streams or gambling in LV for a week!

-Barry

 

[Mexican Hermit]

It would be around $587.00 bucks. That is a lot of dough. Do you really think it is worth it? (no offence).

Or buy 1 single control with the stream and $369.00 worth in anther toy?

 

[photobarry]

Well, what's in your tank coral-wise? I think that a lot of corals would really appreciate the flow that the streams provide and I will probably get a second one at some point. I am just setting up my tank and have only run mine for small periods of time. I have to wait for the sand to develop some life before I can let that puppy rip. Based on the small amount of time I have had mine running it looks like over half the tank gets really good flow coming from the stream. All that water that the stream is pushing must make it back to the pump, so there is also some really nice flow coming back towards the pump. Kind of hard to explain. The one really exciting thing was that when I was running it in the pulse mode ripples were developing in the sand. I had never seen that before and it looks really cool. I only have 2 pieces of rock in the tank right now so I don't know what the flow will look like when it is full of rock. Your aquascaping will really determine what the total flow patterns and need are in your tank.

I just started my tank a couple of months ago also. I only have two tangs in there and 200 pounds of live rock. I really prefere fish but I do intend to have a couple of inverts and corals. As you say maybe I can buy the stream with the controler and later on get the other stream.

 

[Mexican Hermit]

Photoberry,

Is it possible to program the controler? Or do you have to do the operations manually?

 

[photobarry]

I only have a single controller so I don't know what all the functions on the multicontroller are. On the single controller you can control how quickly the pump pulses and what the maximum and minimum percentage of power the pump is run at (from 30-100%). These are all controlled with dials on the controller. I presume that on the multicontroller you would also get to control how quickly it switches between the two pumps. Its really easy to setup and to change.

What I do not understand is the following:

This is what Tunze says:

Currents are an energy of life in your aquarium. Turbelle Ã"šÃ‚® electronic circulation pumps are controlled electronically. TUNZE Aquarientechnik have developed a large range of control accessories to simulate the various current conditions in the sea.

(A) Wide-spread current - Turbelle Ã"šÃ‚® pumps produce a wide-spread (soft) current.

(B) Wave simulation - The maximum and minimum output as well as the pulse time of the pumps can be set easily ââ"šÂ¬Ã¢â‚¬Å“ separately for the two channels in Multicontroller 7094, and for one channel in Multicontroller 7091.

(C) Foodtimer (7091 + 7094) - The pumps can be switched off by the push of a button. Automatic restart after 8 to 10 minutes.

(D) Operation in night mode - The output of the pumps is reduced during the night. The photo-electric cell 7094.05 required is supplied along with Multicontroller 7094. The photo-electric cell has to be ordered separately for Singlecontroller 7091.

(E) Sequential pump circuit (7094 only) - The pumps are started one after the other, which produces a swelling current. The switching time can be adjusted.

(F) Tide simulation (7094 only) - The pumps are switched on or off alternately. The switching time can be adjusted between 1 minute and 12 hours.


According to Tunze you have all of these functions for the multicontroler and the single controler.

BUT,

Do the controlers change between (A, B, C) on their own or do you have to do it manually? Is it possible to program the single controler to do 1 hour of A two hours of B, etc.... or do you leave it on A until you later change it to B?

I hope it is clear... :rollface:

A) Based on the design of the pump it is always producing a wide-spread current. Basically, they push a large amount of water over a large area therefor the speed of the water does not have to be as high as a powerhead that only provides flow in a narrow stream. The Stream provides bulk movement of water. By that I mean it is more like waving your hand back and forth in the tank. A large quantity of water is moved over a large area. So to conclude, this is independent of B and C. As long as the pump is running A is always happening.

B) This is where the pump pulses between a higher and a lower setting. Here is their description of this straight from the manual. "Pulse operation or wave simulation: Use the 'Power 1' and 'Power 2' knobs to set two different performances between 30 and 100 percent, which will change after a pulse time of between 1 and 5 seconds, which is on the 'Pulse' knob." That is how the Stream normally operates. You can't set it to stay on one speed for any longer than 5 seconds. It works really nicely. Basically at high speed it pushes a large quantity of water from one side of the tank to the other and then rebounds when it goes to the slower speed. This produces really chaotic water flow in the tank that is quite natural looking. So, basically there is no real programming involved.

C) The food timer is simply a button that you push if you want to turn the pump off during feeding. It will stop and then automatically start 8-10 minutes later. Just make sure none of you fish tries to take up residence in the pump. I'll probably keep mine on all the time to make the fish work for their food.

I hope this helped answer some of your questions.

Thanks,


So basically the pump is always on setting "A". Setting "B" is a setting that is on for moments. Does it work randomly? I imagine that it doesn't work with an integrated timer...

 

[photobarry]

Don't think of A, B, or C as settings.

'A' isn't really a setting, its just how the pump works. A normal powerhead moves a certain amount of water over a very small area whereas this pump moves a certain amount of water over a much larger area. If both pumps pump the same amount of water the Stream would have to pump it at a slower velocity since it is spread over a greater area. That is how they can pump such large gph without having a ridiculously high water velocity.

So, this is how the pump works when you have it set to pulse for 5 seconds and you have the power set to range from 30-100%. Ok, you plug the thing in and it starts running at 100% for 5 seconds and then 30% for 5 seconds. It then repeats this infinitely. So it is not random. I'm not sure if I understand your timer question. It does have an integral timer in that it will pulse every 1-5 seconds depending on what you have set. It is always a set amount of time between pulses. I don't see any need for a timer for this pump.

My copperband butterfly is staring me down so I better go feed it.

I think my little brain is getting the picture :lmao:

A = How the pump normally operates

B = Turns the pump "on and off" pulsing

C = Food timer

D = Photo cell takes care of this

E,F = same as A and B but with 2 pumps

I should right a book: "Streams for Dummies" :lol: :lol:

I noticed you can add a branch to the streams, I guess IT is only a type of extension cord that will make both pumps work exactly the same. Not like the Multicontroler.

 

[photobarry]

I think you got it!
