Tunze Multicontroller

[dement]

Guys,
those of you which are using Tunze pumps with Multicontroller for your SPS tanks, which mode of Multicontroller ( Pulse, Interval 1, Interval 2, Sequential ) you preffer and why.
What are your settings?
Thanks for info.

i try to flip mine around every few days so i have a constant randomization of the flow.

Pulse is on interval 1 with the interval set at around 4 seconds. I have 1-6100 at each end with 2-6000s in the middle pointing the same direction as the one on the side it pulses with. I have "tried" to create a back and forth action. My son likes to play with the buttons, so I get "extremely" random flow.:(

Anyone use the night mode. I have never tried but am thinking about it.

[JetCat USA]

i do, it just turns off pulse mode. if you have them in tide/sequence mode, they continue to swap/sequence just don't pulse.

I'm running mine on interval # 2 with them changing every 45 seconds.

Interval 2.

[mdt178]

interval 2 @ 4 hrs.

[-=DieselDave=-]

interval 2 @ 6 hours.

I'm gonna try that, what makes you guys want to go for the long period? Any reason in particular? I just changed mine for every 2 hours, it's actually kinda hard to tell what the heck you have it at.

As he phrased it to me... and I quote " well the ocean is never constant so him changing it is just like the ocean changing so I really don't mind it" it may not be verbatim but pretty close.

Correction: my settings are Interval 2 @ 6hrs (not 4hrs) with moon light. Per Tunze, these settings simulate tidal effects.

I have it on interval 1 swtching every 30 seconds or so, also with the pulse form 30-100. I recently put it on night mode as well, just keeps it at 30%.

[Henry Bowman]

Rodger on the Tunze forum says that Interval 2 is the easiest on the pumps.

[MJAnderson]

Interval 2, 6 hours.

I read an article a while back in advanced aquarist about flow/light and which is needed more and they made a pretty good case for linear, not random, flow for corals. There was a discussion at MACNA last year talking about how it takes a system like our, with rock and coral, 15 minutes or longer with a consistent flow of water for a 'current' to develop. Just randomly blasting water from various corners doesn't allow this 'current' to ever develop. So I went with 6 hours. You get more flow using the same pumps when you can get a current going since turbulence is reduced.

The only thing I don't like about it is that I have a few dead spots depending on which way the flow is going. Things will settle in the corner until the flow changes sides, then get swept up into the water column.

Interval 2, 2 hours...

[Waxxiemann]

I made the switch for 6 hours, so far I like it.
