Where do YOU place your VorTech MP40?

[Salty150]

Where does everyone put there MP40s (10/60)?

I know most put them on the sides - but where do you find works best?

8" below the waterline and 8" away from the front glass?

 

[jgraz]

I have 2. One on each side of the tank, about 10" down.

 

[Hentz]

I have both MP40's on each side of the glass.

One is sitting towards the front middle of the tank while the other is sitting higher more towards the back flowing over my SPS.

2 on each side of the tank middle way the tank reef-crest mode, anti-sync.

 

[Salty150]

OK, so how far down and how far back from the front glass do yours sit?

 

[Dmorty217]

I have one mp40qd on my 75g QT on the side half way down. I also have 2 mp60s on my 625g on the far side (tank is 7ftx6ftx2ft) those are about 6" away from the side and one is half way down the other is 3" above the bottom

Depends on your aquascape. Also BB or sand? Overflow and return position.
Post a pic of your tank

 

[Salty150]

I am trying to design a new custom built aquarium cabinet (stand, canopy, and sides - all in one).

And I am looking for the farthest people are putting their MP40s from the front of the glass.

I want to know how much side of the tank I can show before covering the rest in wood to cover the MP40s.

The tank is 60" long x 18" wide x 26" deep (24" deep with a 2" sand bed) dual corner flo.

So the width I have to work with is 18"...

I was guessing putting them 6" from the front glass - but if I can get them farther back - the more of the side of the tank I can show.

Hope this makes sense!

I put mine on the back wall, and bounce them off the front panel, flow disperses well that way for me.
Top of my vorts are about 3" below waterline

I would LOVE to be able to put them on the back glass...

 

[davocean]

It's a lot less noticeable in person than it is in this pic, they kind of just blend into the background to me.

Are you running them synced or anti sync ?

 

[davocean]

Are you running them synced or anti sync ?

Non sync'd, in fact the one on the left is an old MP20 that is still running just fine, one day soon I'll swap that out for 40QD so I have complete silence, but even when that happens I most likely will still run non sync'd.

 

[champion6sigma]

What is benefit of running synced? How does it work? My two are now on back wall. Cleaner look if u can get away with it

It is a much cleaner look on the back wall...

I guess I never really understood the reasoning behind the back wall not being the greatest spot for them?

I mean, I get that they aren't aimed at each other - but they are aimed at the glass that is 24" way - and they would make a "rolling" motion when the water hits the glass, etc...

 

[champion6sigma]

Maybe some people's thoughts are that they lose driving force ....sort of like headless with every turn of a pipe....but water is being displaced no matter what ...and flow should be just fine in any tank unless u have a massive tank needing extreme high flow. I don't have any experience with large tanks and mp use. And the backing on the mp40 is so small unless u have your tank built into wall practically lol u should be able to fit it in back. There is one mm between my wall and the mp40 backing. And I've got two of the sticky things with zip ties hidden in back incase of magnetic failure and the back falls .

I do want to try out anti sync... will need to research apex forums and look at ecotech manual

It probably depends on your setup, if corals are stacked high it may be more of a blast at them, maybe.
I purposely scaped my tank as I did for a number of reasons, mainly to provide a high up space for a magnifica sea anemone, and I put a bit of thought into how the flow would hit the front panels and disperse through the tank.
It is kind of a rolling flow that comes back and up towards corals, which is what I wanted, so an even flow faces the magnifica and keeps it facing forward.
It's working quite well for me this way.
It also does tend to keep the sand swooped higher in the back and lower in front, which makes for a nice viewpoint.
The quiet drive on the right has a significant increase in flow compared to the 20 on left, and I had to lay down a couple flat rocks to keep it from welling, when I get a 40 for the left side I will probably turn that one down and balance them more evenly.
I like chaotic random flow, I feel no need to sync to achieve that.

I asked this question on my own thread...but since many of you are mp40's users....is using the wrong spacer really bad for the motor? For example if, based on ecotechs recommended spacer for my tank, should be the "middle size" not the largest one and not the sticky thin paper one..and I then decided to use the thin wafer (non plastic)...would i be damaging a motor....would i just be getting maybe fast spins then what I set at....or would it create no change...

I did just that and I think...not sure...the speeds are faster. Like davoocean...my sand started to pile up on back and get lower in front...I've since lowered my apex set speed....

I've got both mp40's on back wall of cube tank....left side slightly higher than right side. left mp40 with wafer spacer...and right one with recommended...

i initially did this because dry side was falling on left. did so 3 times in a matter of 2 days...has not fallen since...

I also had cleaned out both vortechs and disassembled...incase it was a dirt issue...but the left one fell after cleaning....i do my best to visually see if mp's are alligened perfectly but as you know its harder to do when the back glass is blacked out...with a very thin layer of black material or something to make it not see through..my tank being close to the wall behind it and me having a wall on the right side of my glass. placement is extremely hard to do for the right mp40...

thanks for help..

i tried researching sync anti sync..its still confusing...don't know if you all do it...i may post a query in the apex forum or the ecotech group...

part of me is not sure if the two mp40's when on..are just countering each other to point of where i might be losing flow...

I don't have enough coral to visually "see" what the currents are doing...and my fish don't swim around much in front of tank...even my large chromi, i've got 2 , stay in the rock section in the back...don't know if its flow...or other

Using the wrong spacer can damage the motor. The bearings are designed to work within a certain range of magnetic force. With too small of a spacer, there is excessive force on the bearings that accelerate wear. The prop speed matches the motor speed, so you aren't getting any extra flow.

It is a much cleaner look on the back wall...

I guess I never really understood the reasoning behind the back wall not being the greatest spot for them?

I mean, I get that they aren't aimed at each other - but they are aimed at the glass that is 24" way - and they would make a "rolling" motion when the water hits the glass, etc...

When the Vortechs are facing each other, they can essentially change the direction of water flow at will. It allows corals to sometimes get flow from the left, sometimes from the right. It also helps to minimize dead spots in the system, where detritus settles, because the flow changes direction.
