Vortech MP40, first impressions

[rrasco]

So....I have been debating getting vortechs for my tank. Time to see what all the fuss is about. It's a 105 rimless, 48x24x21. I was considering one mp40 or two mp10s. However, I believe my glass thickness is 1/2". I just confirmed that with DSA. Max recommended glass thickness is 3/8" for mp10. I'm curious, has anyone used an mp10 on 1/2" glass? Could someone either A) test this for me if they have 1/2" glass and an mp10, or bring an mp10 so we can see if it works?

Worst case, I can end up getting an mp40, but I figured two mp10s would provide more random flow patterns than a single mp40.

Thoughts?

[StevenSeas]

I have that exact tank at the shop setup as a display tank. I'll try it out for you today with a mp10 and see how it goes.

[FireWater]

If the dry side didn't weigh so much I would say go for it. Hopefully Steven will be able to give you some results.

[Tempset]

I would get 2 MP40's and turn both down until you get the desired flow.

Then again, 2 of those can add the price quickly. You might just stick with the 1.

I would even touch an mp10 that 1/2" glass. Even if it does hold - would you want to gamble on it?

[350gt]

Won't work....


well it will but I didn't trust it.... Dry side is heavy, you get some bite but any little bump and it will fall. I have 2 40's and bought a 10 for the rear and had to trade it away.....

[ramsey]

Yeah, I wouldn't risk it either. Even if it works it may wear out your wet side prematurely or something.

[350gt]

Get one 40, I had one for the longest time on one side of my 60" tank and it was decent flow when cranked up. You just don't want no Lps such as frogspawns or Duncan's on the side with the pump cranked up....

but at least you get a feel for them without having to buy 2. You can do what I did and just wait for a second to hit the marketplace on here....


now I have 2 and its plenty cranked up half way, I wanted a third just cause.... Don't really need it but figured why not.

[rrasco]

That's pretty much what I figured the response was going to be, just kind of curious since random people online mention they have used mp10s on 1/2" glass. I don't want to risk a $300 powerhead falling to the tile though. I would probably smash my tank in a rage. Okay maybe not, but I'd want to.

One mp40 is not really in the budget, nor two mp10s for that matter, but definitely not two mp40s. Would an mp40 be adequate for a 105 gallon, or would I need to supplement flow?

[350gt]

I was pleased with the 1 40 on my tank....

I prefer it over any power head that just has a straight flow....

[rrasco]

Hmm. That's also what I was worried about, it has taken me forever to perfect my flow so my euphyllias and other LPS or softies don't get destroyed from flow. I figured an occasional blast wouldn't bother them as much as direct linear flow would.

[Big_Pun]

your option will be one cranked up or two for better coverage and turn them down a lil as Tony stated. i have two on 60x24x24 tank at about 75% and get a really nice wave and variable current. i wouldnt set a tank up without one or two or three :)

i was a lil disappointed last night. i was doing the auto tune for a wave in emilys cube and got a nice wave going....... then i noticed the ato was cycling on and off, the float for the ATO is in the tank(bummer), so i had to make lil wave :(

[Big_Pun]

if you mounted the wire from motor to the zip tie pads thingies very securely, that they come with (HomeDepot sells them also) and you trusted them not to fail you could do it. its a risk ....

[Tempset]

Very good point. You could mount the power head with cord going up instead of down(how vortech recommends) & get a very stable connection.

[LuckySingh]

I don't think so two mp10 will be enough any way for a 48" long tank ....mp40 is the way to go

[koa25]

MP10's would be noisy as well. The farther you have the magnets away from each other between the glass the more they will skip or not have a clean connection during engagement and eratic cycles. I did it on my 125 when i first got the MP10 when i was testing it before putting int my 40 (and i wanted to see if i could get a wave in my 6" tank with an MP10) and it made weird noises and looked it up and discovered that happens when they are placed not within specs.

[FireWater]

Robert. I am running one 40 on my tank at home. I will say that I will add another one when I sell my arm and kidney, but I have been able to create flow well enough. Mine is same footprint as yours.

The 2 10s will be noisy and a single 40 will be heard. 2 would be optimum and expensive.

[rrasco]

Looks like most of my limitations and recommendations are leaning towards a single mp40. I could always supplement with one of the many koralias I have, if I have to. Then maybe I can look into another mp40 at a later date. Now to find $500.

Thats what im doing for now getting 1 and on the other side a Koralia , right now im running 6 Koralias hoping to get rid of 5 of them when my mp40 comes in on monday :)

[rrasco]

Well, I bit the bullet and ordered a new MP40W ES. That was hard to swallow, so I'll wait to see how this one works before I contemplate selling my unborn children for second.

[350gt]

Lol

Look forward to hearing your opinion.

haha thats the way i felt for 1 pump 465$ it better work good no not good GREAT !!!

[Big_Pun]

haha thats the way i felt for 1 pump 465$ it better work good no not good GREAT !!!

i will never set up a tank witout one or two. emilys cube even has a mp-10. you take all that heat from the motors out and put it outside and then the power is pretty impressive from them. and you can make waves in your tank and if your tired of that turn it of and it just does random flow.

[rrasco]

I thought I was making a big purchase when I bought two Koralia Magnum 8s (different tank)...but nothing compared to this. I have to say though, I'm pretty excited to see what it can do. I get enough flow from my Koralia's in there now, it's the flow patterns I am most interested in with the Vortech. Now to wait on shipping...I should have just done this last week when I placed an order with BRS. That order is here today!

Unfortunately I didn't have that option with this purchase.

be prepared to be amazed and wonder why you didnt buy one sooner

[Paul28]

Yeh i got mine monday wow its crazy a pump can do so mutch ive been running it in Nutrient transportmode and lagoonal i tryed short pulse im not doing that again my corals all closed haha the pump is insane

[Paul28]

o yeh i found this link it helped alot on setting modes http://www.youtube.com/watch?feature=player_embedded&v=JsCR-7BYWSs#!

[rrasco]

be prepared to be amazed and wonder why you didnt buy one sooner

I always wanted one, but I certainly know why I didn't buy one before now. $$$$$$...my kidney is still trying to catch up since the removal of the other. I'm sure the bathtub full of ice didn't help much.

[rrasco]

I am failing to understand how this is considered wireless.

[Paul28]

I am failing to understand how this is considered wireless.



i think its wireless if you have 2 of them they can work together

[rrasco]

i think its wireless if you have 2 of them they can work together

I figured as much. That's almost useless IMO. I would by lying if I said I wasn't bummed the controller and dry side are wired together. They are supposed to go on opposite sides of a wall.

[Big_Pun]

syncing two together or more if you have more is genius, i get a nice wave and random flow when anti-synced. a lot of people think wireless means no wires to actual motor but dont know how power would get to motor unless it had a battery pack and a receiver. the tunze are nice but they all need to be hooked up to a controller. if you just want a wave their is always a tunze wave box, those thing can rock a wave!

[rrasco]

Syncing I get. I expected a power cord to the dry side and one to the controller, but not a cord between the controller and the dry side.

[350gt]

It's only one cord to the dry side.... Just think of it as the power cord.....


your looking at the negatives.... LoL

think of the positives!

1.no big intrusive power heads.... Mp 40 can easily replace 2 or 3 regular sized power heads and all the cords from them.. Plus the heat put out by them in the tank.....

2. Controllers are always cool, especially with LEDs lighting them up..

3. It's resell is always pretty good

4. No regular power head can do what the mp 40 can...

[Big_Pun]

robert what bugs me is the crappy velcro to mount them.500 bucks and velcro!! i was lucky and got some wet acrylic holders for mine.

[rrasco]

LOL. I know. Somehow when I read wireless I assumed each one was wireless, not just work wireless together. If I had more that sure would be nice. I guess I had expectations and feel let down. That doesn't mean I won't like the pump, just not what I was expecting as far as hardware goes.

Ha. I already noticed that too. I was like, where is that nifty acrylic case Karen had hers in. Oh....that's right!

[rrasco]

After about a week of use, I figured I could follow-up with my thoughts.

Overall, I like it. I like the random broad flow. I tried to run the MP40 alone for a day, but had to keep my koralia 1050 running on the other side of the tank. Feed mode is cool. Not having the cords in the tank is a nice-to-have, but then you have to deal with cords on the outside of the tank. For aesthetics, I actually prefer the cords in the tank, barely noticed them before. Now, with the vortech cords on the outside of the tank, it's much more noticeable. Safer, but detracts from the look of the tank IMO.

Having said that, I'm not quite sure I feel like this is a $500 pump. I could have bought a koralia wavemaker and added a few pumps for this price, spent a little more and had up to 4 controllable DC pumps for a fraction more. Koralias have been great to me, but I wanted more random flow. I think with the price point of vortechs, they could have added a little more, like a wireless controller. That way if you want to run ecosmart, you only need one controller and not one for each pump, even if they do talk to each other. This would have allowed Ecotech to sell the wet/dry sides together and then the controller as a stand alone item. You could buy one controller and add the pump assemblies at will. It may seem like I am splitting hairs here, but for a $500 powerhead, I don't expect good, I expect great. The first rule in marketing though, is never put all the features on the first version, or second for that matter. There will be new vortechs at some point with these features, mark it.

[Big_Pun]

everything has some draw backs, i had the koralias on a wave maker and they do not always start up in the right direction, annoying seeing one in reverse( but i guess that counts as random flow lol). i really like not having cords in my tank and flush mount wet side. buy a second see if you like it more lol!!!

[rrasco]

Everything does have drawbacks, but they have to be less of a draw back with prices like this. My Honda doesn't have leather but my Maserati sure as heck better.

Did you have the wavemaker or the smart wave? I don't know the details of the wavemaker, but ideally you could prevent the pumps from actually turning off, just ramp them up and down like a vortech. Vortechs don't ever actually turn off. The new koralias are not supposed to start backwards, because they have a bump stop, but mine did start backwards once. That should only occur if the pump actually turns off though.

LOL at the buy a second one. Ideally, this tank would need two of them, but I don't think I will justify the cost again. I just don't feel the value is there. Maybe I'll wait for them to read my post and release the new model first, then I'll buy two. :)

[KING]

You say you have a Maserati..but your crying about a 500 daller pump..They are what they are..To me an a lot of othrrs its worth it..an maybe some day they will make them like you were talking about but till then..mp10..40..60..rock.. IMO..lol

[Big_Pun]

it was the newest hydor controller and a brand new k-1400, i set it up for a friend. i use the auto tune to make a wave and save it. then use nutrient extract mode and on anti sync. i was thinking of getting a third one on back glass for some more flow as my sps grows out, to get dead spots and kick up junk from back side, if i keep the 150 up i may.

[Sherita]

I was actually thinking about these for my 210g build. Then I saw them at macna, and could actually get close to them. No thanks, the noise alone would drive me batty. For what they cost they should be a lot quieter than they are. And the last time. Was at DNA they hd a demo running. Noisy too.

I believe I will be going with controllable Tunze's for my next two builds.

I don't have a Maserati (yet!) My point is: when you pay a premium for a product, you expect whistles with your bells. They are nice pumps, but this is my honest review and for $500, I do think they should have more. I know hardware and what it would take to add these features to the pumps, so in my opinion, it's feasible and should be what they are. They are not, so that's really a moot point as of now. As I said, I'm sure it's part of a product development/marketing plan, if they ever implement something like that.

I actually don't mind the noise. Mine isn't loud. Not loud enough to bother me anyways. I have it on reef crest mode, so it only spools up to max speed (user set) for a very brief second, occasionally. I could hear the motor ramp up when it did that. I eventually turned the max speed down by about 2-3 clicks and now I barely hear it at all. I turned it down due to blowing my euphyllia around, not because of the noise. The wet side has to be positioned correctly, otherwise it will make noise.

[Big_Pun]

ahh your talking about the 12v dc ones. no it was the other that works with the reg 1400. that is way too much money for some koralias and you have to buy the 12v version separate and a light sensor for night mode.

[350gt]

So your selling?

[koa25]

So your selling?

LMAO! Nice.

[rrasco]

Yeah, I was referring to the DC 12v version. You NEVER want to run AC pumps on switching relays, it will eventually kill them.

I know the controller is expensive, $350, but once you have that, add up to 4 pumps to it. Funny you say the controller is too much money for some koralias, yet the vortechs cost way more, for the same thing. And each vortech requires a controller of its own. I love my koralias, just wanted them controllable.


So your selling?

I didn't say that. Just giving my review for now. Maybe at some point, but for now I am going to keep it.

[Sherita]

My problem is that I'm one of those unfortunate individuals who can hear ultra high frequency sound (dog whistles?, yeah, don't do that, it hurts). And those pumps generate some sort of high frequency noise that makes my brain hurt. Probably not an issue for 99.5% of folks. But an absolute killer for me. I'd rather spend $500 on something that isn't going to give me a headache.

[rrasco]

FWIW, I really want to give these pumps a try:

Actually, that's pretty much the consensus I've come to reading about the noise they make. Most people don't mind them, but a small percentage of people hear that frequency and it drives them mad.

What noise? Lol I honestly can't hear them over my other equipment...

im sure on demos they have them cranked up for show.. Mine are at 50% now.. At 100% they make noise, barely, but my tank would be a snow globe if I did that...

[Big_Pun]

so l looked around and added up the Koralia 12v you would need 4x k5 to be 200gph more than 2 mp-40's with controller and night sensor your at $853. thats a lot of equipment and wires.

you know this is just constructive debate and i finished my work early, so i have free time.

[350gt]

My old mag 9 was making more noise than my 2 40s... Replaced it with a sicce 4 and no more noise.. Lol


now it's my over flows and skimmer that are making a little noise.... Way more than the 2 40s still....

[Sherita]

I'm going to guess that the folks saying "they aren't noisy" cannot hear the high frequency noise they generate. Only a few small percentage of humans can hear ultra high frequency sound, I'm one of them. Those pumps generate an extremely annoying and unpleasant high frequency noise. I'm glad you can't hear it, and you should be glad you can't hear it, because after a while its just painful.

My overflow is noisy, so are my korallias and my return. But this noise isn't high frequency, so I can tune it out because its either a gurgle, or a low rumble. Imagine being able to hear a dentists drill. Now imagine listening to it all day long because u installed something in your home that generates that annoying, brain hurting sound. There's just not enough aspirin in the world to deal with that.

[350gt]

I have some huge ears and can't hear a thing!! LoL

wow I didn't know that sherita...That must be horrible...

All my debates are constructive :) At least we agree these things should be wireless. LOL

The price difference in the 12v k4 and k5 is huge. Twice the price actually. If I was putting 4 pumps in my tank, I don't need higher flow pumps, I need more lower flow pumps. Either way, it's still cheaper than buying two MP40s.

you forgot 30 bucks and extra wires so it knows its night time lol

BAZINGA!

[350gt]

I can only imagine the mess of wires involved with that set up.....

Sorry on a rimless tank I would only want the cleanest and finest ;)

[rrasco]

BAZINGA!

Vortech's don't know when it's night time, do they? Didn't think so.


I can only imagine the mess of wires involved with that set up.....

Sorry on a rimless tank I would only want the cleanest and finest ;)

I agree, which is why I HATE the wires on the outside of my nice DSA rimless tank. The vortech already has three wires. One from wall to power supply, power supply to controller, then controller to pump. The wavemaker would have one to the controller (maybe one to a power brick, but IDK yet) and one to each pump. If you ran two K6, that's only two wires from the controller. Same as the vortechs and with vortech you have extra controllers. So which one really has extra wires or is it all in the eye of the beholder?

[Big_Pun]

someone didn't read the instructions how to set night mode and adjust how long to stay in it easy as two buttons. maybe thats why you dont like it, r.t.f.m. as my unlce would tell me lol.

[350gt]

Eye of the beholder I guess....

mounted the way I do.. I never notice them.. Actually want to go look now.. LoL

guess I was concerned at one point cause with my pc4s I was concerned about real estate.. And I'm glad 2 pumps can do as much as 4 or more pumps..... Would hate to have to dedicate a whole pc4 or more to just flow.....

[rrasco]

LOL I'm aware what RTFM means. I'll have to go back and read it again, but I was under the impression it's a manual night mode, meaning you have to put it into night mode every night, it doesn't do it automatically. Similar to how it goes into feed mode.

Well, technically, the k8 have a higher advertised flow than the mp40.

[Big_Pun]

Well, technically, the k8 have a higher advertised flow than the mp40.

and the size of a Russian nuclear sub lol

[350gt]

If I had to run koralias I would.....


Never said they are not good pumps.... Just can't do as much as a mp40 or look half as sexy..

[rrasco]

that's my point tony, they do everything the vortechs can and can save money doing it.

not sure what a russian sub has to do with anything.

[Big_Pun]

that's my point tony, they do everything the vortechs can and can save money doing it.

have you seen a k8 mag omg they are huge

[rrasco]

Yes. I have two of them. They're not too bad, but that is one of their drawbacks; I suppose.

[Big_Pun]

so if you had no knowledge of electronics, didn't know cost of components and how to build stuff..... what would your opinion be compared to 2x k-1400 or whatever you ran prior. just seems like base your opinion heavily on if you can build it or not?

[FireWater]

Robert, the night mode is continuous. Once you set it its done.

I was running a 1400 and two 1050 prior. Don't get me wrong, I like the mp40. It puts out water, has a broader flow than the koralias, has a small foot print, the controller looks cool (cool points), and compared to my previous koralias the vortech has a controller. However, I do believe that for what you get, one pump and one controller, and the features that you get over my previous models (mainly controllable flow) they are too expensive. Before I owned a vortech I was a prospective customer who thought they were too expensive. I never owned one so I couldn't really judge it accordingly. Now that I am a vortech customer, I still think they are overpriced for what they are and there are comparable options on the market with comparable, if not better, pricing.


Robert, the night mode is continuous. Once you set it its done.

Reading the full manual I see where it says that. The quick start guide that comes with it is written in a manner which led me to believe it operated similar to the feed mode. The full manual really isn't much better, so thanks for clearing that up.

I guess this is where we are supposed to infer that from, eh?


The first time you use night mode, you must tell it when to go into Night Mode.
