Tunze in a 75g?

[Poppy828]

I am currently running the Seio 820 in my 75g tank. I am considering going to the tunze for the option of having the controller set up the different types of flow since I am limited to always on with the seio.

Will the Tunze be too much flow in a 75g? What is recommended if anything for this size tank? 48"x18"x20".

Thanks for any help on this situation.

It will be probably on the order of 3-4 times what you have now, if the tank is mainly SPS and leathers it should be fine. The model I would recommend is a 6000 and a 7091 controller.

It is mainly sps with a few sps and some soft thrown in for my wife. I also have a mag9 for a return I forgot to mention. I want flow, but don't want the sand blowing all over the place. It is a DSB about 4-5 inches or so.

I do also plan to upgrade to a 180 next year or even a 240. Will these be enough with adding more for that upgrade. I would like to buy now with keeping the future upgrade in mind also.

Thanks Roger.

You can upgrade a 6000 to a 6100 later. I cannot promise anything in regards to the sand, in general a mature sand bed will not move if the pump is properly positioned but it is not impossible.

 

[Poppy828]

Well geeeezzz...no promises??? May have to think about this more then...LOL J/K

I think it is worth a try. If it blows the sand a bit, it's not an issue. Guess we will need to try it and find out. The seio does not blow the sand, but it is less flow than the Tunze I am sure. Has there been any feedback on these units in a 75g? The bed has been in place since April, so it should be mature by now. Maybe not.

Thanks,

I have one in my 75 but it is barebottom, 75 is a very popular size so I think you should have no trouble finding opinions.

 

[Poppy828]

Well hopefully others with a 75g will chime in. Is there a package deal with the 6000 and 7091 controller Roger? Will this controller be able to run more than 1 pump down the road?

Thanks,

Todd

It costs the same as buying them seperately but their is a kit name TS07. For the most part the only reason the kits exist is to illustrate how things work together.

Morning Roger,

Thank you for the quick replies. I am looking at going with the 6000 as you recommend and running it on the 7095 controller instead of the 7091 for the programming options as well as the addition of more pumps down the road when I upgrade. I don't beleive I will need more than 1 6000 in my 75g and just want to make sure that the 6000 can run fine by itself on the 7095?

Thanks,

Todd

 

[rvitko]

It can, you gain almost nothing over a 7091 with one pump- the only added feature is the moonlight. You would need two pumps to make use of the other features.

 

[Poppy828]

Well in that case, I will let my Neptune Jr run the moonlights as I have been and just stick with the 7091.

Thanks,

Todd

Poppy: I am running a 75G BB SPS with two 6000's on a 7094(old version of 7095-no moonlight). I would go with the multicontroller, especially if you are definetely upgrading, cause you'll defintely need more than 1 in the 180. Like I said, I have two, and am still considering upgrading my CL pump for some more flow. Even with sand in your 75, I think you'll be ok, with 2 6000's.

HTH,
Dave

 

[Poppy828]

I beleive I am going to go with the 1 for sure. See how that turns out. Still deciding on the controller. I know I will need it later and would just rather do it now. However, if this is too much for my sand bed then it was money not well spent. Spend the $60 for the 7091 and then upgrade later is not all that bad either.

Still discussing with the wife to find out what we want to do. Maybe just do the upgrade now and be done with it.

 

[rvitko]

Why not start with no controller and see what you think, the pumps do work and can be asjusted even without a controller, they just can't pulse or have night mode or foodtimer.

 

[Poppy828]

So I can reduce the amount manually on these pumps? That I was not aware of.

Thanks,

Todd

 

[rutz81]

yeah, there's a mini adjustment that can easily be made with a smaller slotted screwdriver.

 

[Poppy828]

Thanks rutz.

What is the return policy if for some reason it ends up being too much flow for my current setup? Or is there?

Tunze Stream signal format

Tunze Stream signal format

What is the signal format of the Tunze stream pump control input? I have a microcontroller that can do PWM and analog, but I can't seem to find the specs on the device control. Is that something that Tunze will share? Alternatively, has anyone put the controller on an oscilliscope to see what it is doing? Since I already have the controller working on my system, I would prefer to program it rather than adding a second controller. Sorry if this seems off topic, but it seems like I might have the right group to answer this question.

 

[rvitko]

Unforunately I don't have that information and I know they won't give it out. All I know is it uses an 8V signal.

 

[Poppy828]

Roger...

What if any are the return conditions if for some reason this does not work out?

Thanks,

Todd
