I don't know... i had 2 MP10s ES on my shallow 85g and it was close to enough so I imagine it would work well on a 55g, but my 85 gallon has the same length of 48" and while it worked I did not get the results I was looking for in a wave from the ecotech. Perhaps my width killed it. 48"L x 24"W x 17"H
The single MP40 rocks on my 85g but I hate the old man wheezing noise at 70-100% power. I suspect that noise will be gone when the 40 is tuned down to 20% on my 29g lol
I don't think the 10's have enough umph to go from one side of the tank to the other...4ft is kind of far for an MP10 in my opinion even with them synced on opposite sides of the tank facing one another, they still need to make it to the other end of the tank to produce the wave, perhaps...maybe if they are mounted to the back glass and slam against the front, that might work. The back glass was not an option for me on my 85g due to the foam background.
The 40 can handle the 48" length easily.
But...if you are just after a wave (I was) then get a wavebox. If you are after all the other features of a vortech then I would go with 1 mp40 or maybe 2 mp10s on the back glass. Honestly though I thought the 10s seemed a little cheap. Maybe I just had such high expectations for the vortechs after wanting them for so long that I just wasn't satisfied when I got them.. I was expecting much better hardware. The technology is awesome but the pumps fall short in quality IMO and had I not been able to purchase them through my business I might not of bought a second after I tried out the first MP10, though it was super cool when I got the second to sync. I have read so many amazing posts about these pumps and just feel it has been a lot of hype over the years. Just my honest opinion though.
It all depends on what it is important to you and what will fit with your needs.
