So I got a pair of MP60's in yesterday (to replace the 40's) and right away I had to put one of them in next to the 40 for comparison and boy are they HUGE!
the dry side sticks out soo far, Luke commented that it looked like a big coffee cup.
Here's a full tank shot:
These pumps have lots of flow, when I first put the MP60 in I had it turned all the way down and when it was sitting next to the MP40 the 60 was pushing far more water than the 40 was turned about 75% full.
After putting both of the 60s in and syncing them up on reef crest mode it didn't take long for the water in the tank to stir up all kinds of trapped detritus... I ended up replacing two clogged filter sock in the last 24 hours.
I have settled with dialing the pumps down to about 40-45% on reef crest and may eventually turn them down even further later on.
In retrospect I should have heeded Paul's warnings that the 60s are too big, they are definitely unnecessary for a 120 gallon... one may be alright but 2 is way overboard. However one thing I notice right away was that I don't hear the noise that the 40s inherently have when decelerating, that was replaced with an entire new humming sound which is far less noticeable than the 40. next thing to do is get that modded maxijet and K2 out of the back of the tank.
