Dual Vortechs?

Dartolution · 01/25/2015, 03:15 AM

So, I have one of the Vortech mp10s on my 40B right now and I am wanting to create that gentle back and forth movement you get in the open ocean... Not that fast up and down movement that one of these pumps operating in fast pulse mode provides.
Would two of these mp10's in a anti sync long pulse mode give me that gentle back and forth motion I want ?

Opinions? Experience...

oseymour · 01/25/2015, 07:24 AM

Yes they would, if you have the wireless versions and you sync them, you can create a wave motion.

I have 2 on my 37 and I have them in reef crest mode and for a couple hours a day in nutrient transfer. It does a good job of the wave action.

tkeracer619 · 01/25/2015, 10:33 AM

Yes they would.

Dartolution · 01/26/2015, 01:28 AM

Its not just wave motion that I want, I can get that with one of fast pulse mode...
I want that gentle back and forth slow swaying you see on the open reef.

Any videos of this?

ca1ore · 01/26/2015, 09:47 AM

Would they? Next time I see a tank with that gentle back an forth (like in the ocean) will be the first time. A physicist friend expanded to me long ago that a home aquarium is simply too small to generate a slow wave (a bit like trying to get 25hz bass extension in a small listening room). That's why you always see that rapid slopping back and forth.

Sinekal · 01/26/2015, 12:16 PM

The closest I have seen is from the tunze wave box...I agree it could be really challenging in our closed environment given the force needed to create the wave and the limited area for it to spread/dissipate

Dartolution · 01/31/2015, 09:41 PM

Stop thinking about a "wave" and start thinking about alternating flow. Then it becomes possible.

Push flow from left to right for X time, then from right to left for X time.

Essentially I want to put them on long pulse mode for maybe a minute each back and forth..

See what happens now?

can two wireless Vortechs do this?

Wazzel · 01/31/2015, 09:57 PM

That genial back and forth is wave action. Not going to happen in an aquarium.

Dartolution · 02/01/2015, 11:19 PM

So you're telling me, that even with two vortechs in long pulse mode alternating between them this isn't going to give me that back and forth motion?

Do the Vortechs anti sync when in long pulse mode?

Wazzel · 02/02/2015, 07:24 AM

It will give you some sort of back and forth, but it will not be like what you would see in the wild.

Frozenguy · 02/02/2015, 08:17 AM

The wave you seek has too long of a wavelength for our tanks.

The best you can do is a higher frequency back and forth motion that you've probably already seen.

tkeracer619 · 02/02/2015, 04:11 PM

Ah I guess I misunderstood. It's very difficult to get a good surge going which is the slow back and forth you see.

I assumed since you wanted slow back and forth you were asking if they could be made to duplicate that. They can but you need to setup the tank in a gyre fashion such that one pump can spin the tank one way and the other can spin it the other. In terms of sloshing the water back and forth slowly no, it isn't currently feasible in our tanks.

Cayman · 02/02/2015, 06:36 PM

I don't want waves in my tank, that is usually the sign of an earthquake! I think what the OP wants is back and forth flow. It may not show up as a "wave" on the surface, but the change in flow is there and that is what counts.

Frozenguy · 02/02/2015, 08:02 PM

Let me put it a different way.
The oscilation frequency cannot be low like the ocean in our tanks. It can only be of higher frequencies.

ReeferSutherlnd · 02/02/2015, 09:38 PM

You could get a bunch of pulsing Xenia, those just naturally slowly pulse and are very appealing!

Wazzel · 02/02/2015, 10:00 PM

Also keep in mind the water creating that back and forth motion is actually moving in a circle.

With the new Jabeo wireless pumps, you can almost get a long wavelength wave mode going in C mode with 2 pumps in synch, but its not going to be anything like the ocean. It is much better than I could do with my Vortechs. That being said, I am not recommending that you go out an buy the Jabeo pumps. Im actually going to be selling mine because even though they are a pretty awesome pump for the price, their random flow mode is not anywhere as good as the Vortech pumps. But they are 100x more quiet than my Vortechs. Im thinking of giving the Gyre a try.

EXACTLY!

This is precisely what I am aiming for.

back and forth gyres within 4-5 seconds of one another roughly.

I have one Vortech more aimed toward the back middle of the tank, and I plan to position the other toward the front middle opposing.

Has anyone tried this?
