I had a similar delimma couple months ago with my new tank (36x24x20). I have 2 mp10s from my old tank but I was advised that they may not work properly on 1/2" glass. So I used this as an excuse to get an mp40. Although the mp40 worked well on just a water test, once the rocks were in, I had a number of idle spots. Disappointed with the result, I tried my old mp10s and to my surprise they work marvelously. By placing them in different spots got rid of the idle areas and have a even distibution of flow. BTW, I believe they now have package deals for 2 mp10s.

Thank you for this!

What about 2 MP20s? Aren't the mp20's upgradeable to mp40? That way if you ever upgrade you will be ready. It think they may have been discontinued though. Maybe someone will pipe in on this one. If so, you might be able to find a used one.
 
If you were on a budget maybe a 20 that could be upgraded later, or 40 now.
It is possible it won't hit EVERYTHING w/ just one, and part of decision should be based on what you plan to keep.
I threw in a tunze 6025 modded to hit the dead spots my vort didn't cover, and did so for cost and ability to aim.
 
The best thing for your tank would be 3 mp10w ES. One on each side, and one on the back. This is how they were designed to be run. There are some really good deals on mp10's out right now. I would just buy 3 regular mp10's, and 3 upgrade kits. Total cost will be about the same as 1 mp40 and 1 mp10, but you will have much better all around flow.

If you're on a budget get 2 mp10w ES now and add another one later.

My tanks is a cube 24x24x20 and plan to have 2 MP10s on the back wall with the overflow in the middle. In my arrangement, one MP40 would not as efficient since I don't have a long tank. I feel one MP40 would leave dead spot on the other side of the overflow.

I had a similar tank w/ 2x MP10's.. Even if I went with a full, SPS dominate tank, it was still TOO much flow (IMO) when they were all the way up.

Another thing to look at is you're able to turn down the MP10's to a much lower gph vs the MP40w, which can 'only' be turned down to 1000 gph.

The only time I'd suggest going with 2 MP20's or an MP40w and MP10 is if you were going for an SPS dominate tank.

You could always buy one MP40w and add more later, when your corals grow in.
 
Thanks to everyone who has offered advice and opinions. Based on all the things that I have heard, I am leaning more toward two MP10s. I like the idea of having them both on the back wall, but on opposite sides of the overflow. I think that between that and my return (500-600 GPH) I should have enough flow to keep most anything I want. I have never gotten into SPS too much, but was hoping to start, and like people have said, I could always add another one later.

I do think the MP 20s are discontinued.

Also, whats the advanage of wireless? If they are both on my back wall, does it matter? It seems to me that having it be wireless would be a hinderance more than a benefit. How does the drive unit get power? Batteries; or does the cotroller actually transmit power? I know that's possible, but would have thought it too expensive. I could not find the answer on the EcoTech site.

The wireless is used to communicate with each other. One is a master and the other(s) a slave. If you have wireless, they will work with each other in the different modes. This is especially important in the NTM (nutrient transport mode) and the other new modes. You can also change the modes on all of them by changing the mode on just the master. Also, if you happen to have a Neptune Apex Controller, you can buy a wireless addon that lets you communicate and control the power heads.

Ohhhhh.....so obvious once I am told!

Thanks...I guess that makes wireless pretty much a necessity. I was puzzled why all the pics of the wireless models still had cords. Figured they just used the same pics.

Thanks!
 
you can get mp10 brand new at socal tropical for $150. I see used ones listed in the for sale forum for $140.
 
I just got an email that if you purchase an MP10wES new, you can upgrade your older MP10 to the wES at half price (with a rebate) through Ecotech's store.

They have. I've heard the "regular" MP10 and MP40 are discontinued as well. They're only going to be selling the remaining stock of the above and then only sell the ES models.
 
I've read in a good 5 books that it's better to have allot of small pumps, than one big one, so i go for the 2 mp10s.
 
48 votes and we are dead even. I think Mmckibben has a good point. Logic would tell you two outputs for a given flow of water is better than one. Why do you think people split their return into two locklines?
 
The only thing I don't like about the MP10 is that it's not upgradeable or able to sink w/ others.
That's why I like the 20 or 40 better.
 
I have read that it can't sync as well.

If it can't sync with others, then whats the point of having that one in a wireless model?
