2 - VorTech MP10 or 1 MP40

Fishguy622 · 11/27/2016, 08:36 PM

Looking to upgrade to VorTech wave makers, I have a 75g and was wondering if 2 MP10's would work better then 1 MP40?

Dice750 · 11/27/2016, 08:46 PM

I would say 2 MP10s if your glass isn't too thick. I had 1 MP40 in a similar sized tank and it wasn't enough flow to get to the other side. I bought a second MP40 and now the flow us much better.

BrettDS · 11/27/2016, 08:51 PM

I agree. I had a 75 and I started with a single MP40 and found that the current was too strong on one side of the tank and not strong enough on the other. I returned it and got two MP10's instead and that seemed to work much better.

However, I still wasn't perfectly happy with the MP10's either. I found the the current right next to the pumps was too strong and I couldn't really place anything there. When I upgraded to a 220G tank I got a gyre instead and I am much happier with it.

mpderksen · 11/27/2016, 08:55 PM

My second MP40 will arrive Thursday. First I had an MP10 in my 4' 75gal. It was "okay" with a cheap WP25 on the other side. When I changed the 10 for a 40 (needed the 10 for another tank) and cranked it up, I was AMAZED at how much detritus it stirred up. However, since the right side WP died this week, I can clearly see that a single 40 isn't enough. But I've already seem that a few 10s don't cut it either. (Since the flow of the now dead WP25 is roughly the same as an MP10, in my experience).
To answer you original question, I would choose a single MP40, since the reality is you'll want 2 of them eventually.
If you are 100% sure you will never get a bigger tank, or have funds for a second 40, then 2 x MP10 are the best of the two choices.

Fishguy622 · 11/27/2016, 09:24 PM

I like the idea of having two VorTech so they can work work together instead of just one with a cheap one on the other side. With 1 MP40 would the flow be really strong in front of the pump as to 2 MP10's working together? I think the glass thickness is ok, my 75 is a standard AGA tank. Pretty happy with my tank size, and even if I upgraded in the future it would be big like a 150 or more so I probably would need two MP60's!

CindyK · 11/27/2016, 09:55 PM

Similar experience to others here. I have a 75 gal with a single MP40, it isnt working well. I've tried both back and end placements, it's too strong close to the pump but not enough on the far end. When I placed it on the back wall I got better flow on the ends but a big divot in the sand just in front of the pump. I moved the MP40 back to one end and added a no name power head on the far end until I can add purchase an MP10. I think another MP40 would be overkill.

24x48x16 display tank (80gal) and i use a mp40 on one side with a mp10 on the back glass. Both are set to run at a max of 50% and it works well for my mostly LPS with more flow available if needed. I dont think 2x mp10 would be quite enough and 2x mp40 would likely be too much unless fully sps.

homer1475 · 11/28/2016, 06:37 AM

I have 2 mp10's and 2 jebao pp8's in my 80G cube.

Fishguy622 · 11/28/2016, 09:13 AM

I'm thinking of maybe 1 MP40 on one end and 1 MP10 on the other end. Here's what I'm thinking, one side of my tank has most of my SPS and the other side and bottom has LPS & Softies, I believe I should put the MP40 on the side with the SPS and MP10 on the other side! Dose this sound right?

Spiffy · 11/28/2016, 10:03 AM

I have a standard 55 long and tried the same set-up. In the beginning, I had just a single MP10, and that wasn't enough. I purchased an MP40, and was running both a each end of the tank. I couldn't get enough flow on the MP10 side of the tank without turning it up to a high setting and creating a divot under the wet-side assembly. I then purchased a second MP40 to replace the MP10, and moved the MP10 to the sump to move things around down there. So far, the dual MP40's are doing well in the tank at about 60% max power in Reef Crest Anti-sync Mode. I am thinking about moving the MP10 back to the DT and positioning it in the rear-middle of the DT in between the MP40's so I can have high-movement at low intensity rates. I plan to run the MP10 at constant speed, but have the MP40's set to Reef Crest Anti-sync. You guys think this might work?

ktownhero · 11/28/2016, 10:15 AM

Get a single MP40 for now, and then save up for a second one down-the-road.

Fishguy622 · 11/28/2016, 12:51 PM

Thanks for all the advise, I really appreciate it! Well I bit the bullet and bought two MP40's, I figured if I ever upgrade I'll in a better position. Also I can turn them down if they're too powerful! Can't wait to set them up tonight!

Interested in knowing how this works out for you, I'll be making a similar decision closer to Christmas.

Is this in a mostly SPS tank Spiffy?

it's a mixed reef with most of the SPS on one side, I can turn that pump up higher then the other!

mpderksen · 11/28/2016, 02:41 PM

For reference, here is the Apex setup for my MP40 on the left side of my 75. The second one gets delivered this Thursday. Unclear if the Apex will anti-sync them yet.

This was definitely the best option, expensive at first but you won't regret it down the line.

Yes. Just couple of pieces, though. Still got some work and skill building to do.

mpderksen · 12/01/2016, 08:57 PM

Second MP40 went online today. Connected to the Apex in seconds. Same default schedule as the other side. When I kick then both up, I pull detritus from all over! Letting the Apex do that daily has got to be good for getting the junk down to the skimmer....

garyinco · 12/01/2016, 10:40 PM

I'd check out Ecotech's calculator at http://ecotechmarine.com/calculator/. You can experiment with different scenarios. I believe your glass thickness is 0.28125".

Two MP-40's in a 75 seem too much to me. I have two in a 105 and I have to some times of the day operate them lower than what is optimal. Just my opinion.

Fishguy622 · 12/02/2016, 08:50 PM

Well it's been a few day with both MP40's going and I very happy with the flow, I have them under 50% power! If I ever decided to upgrade in the future i'm set!

Thank you for reporting back, much appreciated.

Did you place them on opposite ends of your 75 gal? What mode(s) are you running them on?

TIA, Cindy

I have them set up on opposite ends of the tank and I set them to short pulse mode to start! So far I like this setup but may play around with the other modes!
