I found this while trying to find a Jebao dual controller. I think it's better than the Jebao dual controller! It lets you control the intensity on each pump by 1% increments instead of just 100%,75%, or 50% with the Jebao controller which is awesome. I can now get the most flow to keep the tank inhabitants happy and not cause a sandstorm. You can use it with any combination of Jebao pumps. A Wp25 and a Wp40 for example. You can set the two pumps to the same intensity if you wanted. Another awesome feature is night mode. I can program night mode and lower the flow by setting a time instead of by a light sensor.
Right now I have two individual Jebao controllers and two Wp25. I just recently added the second Wp25 and its not working out. I'm getting sand blown around and some corals getting too much flow no matter where I move the power head. One power head alone was leaving me with dead spots and detritus build up. Here's the site with more details http://www.joejaworski.com/jebao/details.html I just ordered mine and will give an update review when I try it out.
