Are the 40s and 60s both at 40%?
Im considering adding a MP60 to my 9 foot tank for some much needed flow. Looking for any reviews good and bad. Theres not much out there...
I think you are better off putting a closed loop or using little powerheads spread out in the back of the tank
Yeah my hesitation was the noise of the MP60s but i like the clean look
With 1" you're going to need the MP60 or a high-end Tunze. I have the MP60 but it is loud. Flow and undertow is amazing though. If you don't like loud don't get an MP60. They are way louder than the MP40.
There not comparable, azjohnny. There is hardly any undertow with a Tunze.
what I find hilarious is people saying MP's of any size are noise makers, I spend 20 minutes or so each perfectly aligning mine sure, but they are ALMOST perfectly silent. I have had many people over with mp10's look in my tank and ask why I have my 40's turned off...I point out they are running at 100% each, they call bull so I have to open my stand to let them look at the controllers...
My point is these can be totally livable IF you take the time to set them up correctly. I really wish I had a directional mic I could use to make a vid for youtube showing how to get them perfect.

MP's are louder than the competition...more than several have noted the 60 is much worse than the 40. This has been my experience as well.
Worth considering IMO depending on the design and layout of the tank. Powerheads would be my personal preference.
"Ultimate clean" is a Tunze Stream mounted in a Tunze Rock - not something hanging off the outside of the tank like a giant wart. IMO
Not entirely accurate. All the Tunze pump magnets are upgradable - so get the size you want/need! (I think Seios may be the only other make with this option.)
Flip, not sure what happened in your tank (every one is different), but the undertow is stronger as well as more effective with a Tunze as the water carries more force for the very reasons you have suggested there is less. Stronger due to the nozzle giving a little focus to the flow and more effective because the intake water has less "reprocessed" water due to the nozzle throwing processed water further away from the intake.
Tunze actually posted a great vid on YouTube that demonstrates the effects visually so it's easy to see. Search on YouTube for "tunzeus flow and turbulence" to locate the vid.
I don't see why it's ok to have to take 20 minutes to silence a brand new pump...one more on a list of too many downsides for the price in my book.
If budget were a concern but you really want the fat, stubby flow of the mp40 (maybe you want 3-4 mp40's across the back?) I may suggest the Korallas. For the price you get reasonable performance but zero frills.
Given you're shopping in the aisle you are I'm thinking budget at least isn't your leading requirement...
For a long, relatively narrow tank, I don't think I could really recommend anything but Tunze. The flow pattern just fits. Also, economy is good, flexibilty in deployment is maximal, durability is very good and replacement parts are reasonably priced. The option for anything like a Tunze Rock is unique to this line of pumps if hiding your water movers is really high on your priority list. My guess is that Rocks would not be required for satisfactory aesthetic results.

Well i got a MP40 and a MP60. MP40 noise isn't too bad and has decent flow. I set it up behind my rock to keep the back clean.
The MP60 is LOUD. Even at 20% its obnoxious and can be heard across the room. Ecotech confirmed it sounds defective, working on getting it fixed or returned in general.
I went through the same ordeal, your new one will be just as loud. Trust me, I had them replace my dry side 3 times for the same reason, it's just how they sound. You need to just return it and get something else!
Does it sound like a power drill kind of?
Im thinking the same. Im waiting to hear back from MarineDepot on returning it. It looks like the Tunze 6255 might be out now. I was trying to go cordless but I think this is gonna be the way to go.
