Just thought I'd pipe in here as well... I grabbed one of these for my new 90g build. The pump moves a lot of water, that's for sure. I've got it running on Other mode without taking the voltage down at all (have a variable power supply on the way) and it took quite some adjusting to find a spot that it wouldn't piss off the couple LPS pieces I have in here so far. I think I've settled on placing it near the bottom of the right side panel, close to the back of the tank, so that it is blowing behind the rockwork. My return and a Koralia are pointing the other direction to create a circular current, and the Jebo has the effect of modifying the current speed. Ie when it pulses up, the whole tank current becomes more powerful, it goes down, the whole tank experiences a small lull in intensity.
One thing I'm not a fan of is the bracket, it's very easy to knock the pump out of position. When the pump is sitting correctly in its cradle, you can feel the socket ratcheting as you adjust the angle of the pump. But it's easy to knock it out of the ratcheting position, and then it kind of free-floats in the cradle and becomes very unstable. It will stay in place but doesn't feel very secure.
