I really want to run the mp40 on nutrient transport mode and make that wave motion, but as far as it possibly breaking my tank that got me really nervous. is this a real threat? how can i tell if my tank can hold up. i bought the tank used so the only thing i know about it is it was built in 2005 and its been holding water ever since, and i have had it running for a year now.

if you get lots of water on the floor..it was too much of a wave..lmao

I run with a 1/4 inch wave going on, its wonderful and great surface agitation. Didn't even know i had to worry...
is it unheard of to have just one mp40 on an 75 gallon sps tank? i took my friend robs (jaftica) advice on putting one of my hydors on the opposite side but i noticed the flow was way to harsh so i took it off. i am running the mp40 at about 70 percent and i see movement on all the corals,sand bed and the top of the tank. should be enough?

That is a very good question. I am in the same boat. I have never had mp40 or mp60s but want to try them. The more I read , the more nervous it gets.
The only thing that I am thinking to do it get the Apex module to control them. Then run the wave 4 hours a day and rest run in reef crest mode.
Also keep in mind that when running in wave mode (nutrient transport) these things get really noisy and annoying.

and i tried doing the toning of the wave but couldn't see any difference when i was watching the tanks wave. i like how it is on factory reset maybe ill just leave it there. theres so many options its overwhelming lol.
honestly sunny my tank is in my room, and the noise doesn't bother me one bit. i actually think its kind of silent, and i am 24 so i am not deaf yet lol. and i tried reef crest mode but again the flow seemed so harsh not the gentle wave motion the NTM mode has and then it goes into a chaotic flow anyway it seems like you get the best of both worlds in NTM mode.

There is no reason to run in NTM all day though. There are many people who run it in NTM in the night after they feed. The idea of NTM is to suspend the waste in water column and then with the surge get it to the overflows. This also mimics the high tides. Then after 2:00 AM run in sleep mode for next 8 hours

How can you comment on this if you have never owned one? Not to sound harsh but it's post like this that causes problems, a person who has never owned a product but is giving a review on it.

Which part of this sounded as a review?? I already said that I am reading up on it. I am sharing what I read. I honestly was trying to help and share my opinion. There is no review here. I said what I would do if I get one.
You said what you heard and also that it was fine to put it in sleep mode at night. Tides dont sleep at night so why should the current in your tank? Also there is no real need for the wave action in the tank either. Reef crest mode with the ramping up and down in flow is perfect. I believe thats the mode, mine is set on yellow #2. Perfect flow for the tank

Yes, I said that "I will put it in sleep mode in the night". Why? Because based on numerous citations and experiences it helps the fish adjust better to aquarium life. In wild they can find lower flow areas to sleep which may or may not be always available in captivity. Of course you would know this if you did some read up. I did not say there is a "need" for wave action. But is that not the primary question the OP started the thread for? If the OP is asking will a tank fail if you run wave action, I am trying to address that. If you read the thread the OP seems to have already tried to run in reef crest mode and found it too violent for "his setup". He asked a question and I am trying to answer that since I am reading up on that too.
Again, reading up and gaining knowledge is a virtue. It is upto the individual to decide how much reading is enough, because I honestly believe that in this hobby nobody knows everything.
As far as what I said about how the NTM works, it is well documented on ecotech website.

Okay, I got nervous about the wave breaking my tank too, as to create a wave, you must get the frequency of the wave to *Somewhat* match the natural frequency of the tank. So I asked my physics teacher. He says that in order to break the tank, or dislodge the silicone from the glass, the frequency of the wave must be incredibly high. To let me get a bearing he compared it to sound. You know that rediculous frequency you need to shatter glass? You need that frequency, in waves. I believe that ecotech must put that statement in the manual to release them of all liability as anything is possible. Im open to the flaming as Im sure ill get some, but I trust my IB teacher more than what I read on the internet about it.
Needless to say, Im running the Mp40 with about 1/2 inch waves and am totally confident. If the waves are rocking your tank, thats another story I believe.

i have 2 mp 40's one master one slave running nutrient export 24/7. The master is running at around 60% 3-4 inches from top of tank. Slave running at 30% at 5-6 inches down from top of tank (opposite sides). At this rate i get nice currents with great surface agitation which i desire...I cannot run my 40's at 100% each cause the water will flow over which is not wanted. You do not need a controller IMO. One more thing, if aligned correctly, mine are dead silent while running really hard...

That is some very good info my friend. After all it all comes to physics. Given that you can control the time of the first phase (which creates the wave) it would be great to understand how long that should be. There are reefers who run the vortechs on short and long pulse and still get some wave effect.
yea i like the NTM mode but when it goes into the surge mode, is there any way to shorten the length of time of the surge? or a way to make the surge less harsh i am going to play more tmw to see if i can dial in the reef crest mode as well.
