Got the Vortech MP40w installed. Took a little adjusting and learning it is not a good idea to stick those cable holders they come with to the glass until you now that is where you want the powerhead. Had to use a razorblade to take one off and it wasn't easy. Koralias are removed, looks like I have two eyes in the back of my tank where they used to be on the overflow box. Vortech is set to about 90% power on a short pulse cycle and is making about a 1-1/2" wave in the tank now. Cool, but actually kind of distracting because my canopy doesn't cover the waterline all the time now, so I get the light coming though the glass on the low spot of the wave.
Initial impression. Cheap controller box, and the motor is right at the level of being abnoxious but just livable. 5db more and I don't know if I could handle it. Think of the sound like a quiet version of a street motorcycle taking off really fast in first gear then stopping, every second. Hard to describe... or type out the sound.. lol.. It is the motor making the noise, not vibration from misalignment. Definately lots of random "ocean" type flow now, corals swaying back and forth. I don't think I can honestly say it is worth $420 though.. $300 maybe.
