Aquasurf and Tunze help

[criecken]

Need suggestions on commands to get a good pulse like flow.
I have spent many hours over the weekend trying different combinations of commands and getting very limited results.
Details:
125 gal tank, 6' long and 18" wide
2 - Tunze 6000 powerheads on each end of tank, near top and pointed towards the opposite end.

Current commands that are the best I could come up with and provide a great pulsating action, but the pulse is way too fast back and forth and not very natural looking.

If Time > 0 then TZ1 PF1
If Time > 0 then TZ2 PF2
Pmp Mode sD for PF1
Pmp Int 30/100 for PF1
Pmp OSC 0/4/5
Pmp Mode SD for PF2
Pmp Int 30/100 for PF2
Pmp OSC 5/4/0

I know this looks similiar to the sample giving in the Aquasurf manual... after all my trial and error I ended up back to this with the very short OSC times.
Next best setting was the same as above but using:
OSC 0/9/10
OSC 10/9/0
but this produced a very slight pulse/wave effect.

[criecken]

no one?

I cannot tell what you want to have; do you want more aggressive waves or more random waves? If you want more aggressive waves a smaller time might be best, more random larger times.

I found it easier to tune 1 pump at a time and then once you have the resonance time for the tank copy the setting inverse to the opposing pump. You will know when you hit the resonance values because all of a sudden the wave will 'jump' in height but it takes a lot of trial and error and a PC close to the aquarium is VERY helpful!

[criecken]

actual wave across the surface is not important to me... but think it goes hand in hand with what I wish to have...
a somewhat slow pulsating flow that will:
1 - keep things suspended in the water
2 - move my anemones, xenia, lps, etc ... back and forth in a natural rocking motion.
I watch the video on the Tunze Wavebox and other than the actual surface wave... I want to accomplish similiar flow thru out the rest of the tank.

try this:
Pmp MODE SD for PF1
Pmp Int 030/045 for PF1
Pmp OSC 30/15/00 for PF1
Pmp MODE SD for PF2
Pmp Int 030/045 for PF2
Pmp OSC 00/30/15 for PF2

copy/paste

you have had success with this on a 6' tank?

[MplsMan]

i have a 5' 110 wks great for me, like said you can tweek for more flow.
change the pump int to a higher # then 30 that will keep it at that for 30 seconds

[criecken]

ok, so the OSC of 30/15... you were meaning:
30 seconds/15 seconds
NOT
3.0 seconds/1.5 seconds
??

I assume via the MODE SD ... capital D forcing the OSC times to be divided by 10... making 30 = 3.0 and 15 = 1.5

[MplsMan]

yes that would be correct
30/15

[criecken]

so doesn't the use of "MODE SD" actually make the time 3.0/1.5?
I thought you would have to use "MODE Sd" in order for it to actually be 30/15

[MplsMan]

from what i sent you is what i have miine set up, i had a guy help me with mine and his wks the same way i just adjusted it some, so i'm not sure what the difference is.

[maroun.c]

I would also experiment with different pump positions:
- Height level in the tank if possible
-Aiming towards each other VS towards mid fornt of the tank with both positioned on upper back.
-one from upper front and another from upper back
-Synch or anti synch if that's available with the controller.

In addition to that pulse sequence and pump power combination are somehow important I get a better pulse motion with my pump on around 70% power with a short pulse 'butthat's with a different pump than yours.

criecken did you have any success with this?
I am in a similar situation.
I have a 210g (72"x24"x29" LWH).
I am running 2 x 6105s on one end of the tank (Peninsula Setup).
Using the Aquasurf I am only getting smallish waves right now.

Complicating matters is my return lines enter at the far end of the tank from the 6105s. I have not tried turning off my return yet, I need to do that to see if I can find the right resonance.

I have tried the suggested value: 00/12/12 with only 1/2" waves.
Starting at 00/08/08 I have increased all the way to 00/18/18 and a number of variations in between. So far with no better results.

The best result so far has been 00/12/13 when using the following program:
Pmp MODE SD for PF1
Pmp Int 030/100 for PF1
Pmp OSC 00/12/13 for PF1
Pmp MODE SD for PF2
Pmp Int 030/100 for PF2
Pmp OSC 00/12/13 for PF2

Keep in mind I have both pumps on the same end of the tank due to the peninsula setup so I am synchronizing them instead of opposing them.

the 6105 is much stonger than the ones I was using (I had 6000 not 6100's).
first of all ... I know you want them to run on same intervals since they are on the same end of the tank so I think you need to change following cmd:
"Pmp MODE SD for PF2"
to:
"Pmp MODE sD for PF2"
you already have the OCS the same on both, but you need the "sD" to keep them in sync with each other (I may be wrong on this, but that is how I understand it).

I am currently running OSC 00/09/10 and I get a small wave. but good flow.
But I think if you try OSC 00/04/05, you will get a very large wave, but it will be very fast as well.

I put a 6105 on one end of my tank and turned the other pump off completly... ran it on the OSC 00/04/05 by itself and the water almost splashes out of the tank!

I have since toned it down and put the other pump back in opposing direction and went to the 00/09/10.

Let me know what you find out as I am curious.

[MarineFishGuy]

OK, I copied the other guys code and updated it.
You are correct, I am using sD, I missed editing that,
I have watched the lights on the Aquasurf, they sync up after two cycles.

I have not tried the times below 00/08/08. I will give that a try and see what I find.

I have my pumps placed about midway between top and bottom.
The overflow box is right above them, so I can only raise them up another 3-4 inches.

I do not want them too close to the surface as I am trying to get the detritus to flow back along the surface.

I will let you know what I find out. I have not found many other people with 6' tanks trying to make waves like this. So getting feedback has been a challenge.
I also think the 29" going against me.
When filling the tank I was getting a 2" wave with a single 6105 until it was about 2/3rds full.

[criecken]

too big of a wave will make your overflow box act weird.
