Jebao Twins Controller (dual pump controller)

[Treebeard]

I have had a WP40 for sometime now and recently added a WP25 and mounted it in the opposite end of my 90 gallon tank. I have them both running in the W1 wave mode and the wave they make is awesome. Not sure why or how but they seem to be running in synch without any dual controller. It is a much better wave than I ever could get out of the pair of MP40s I had before. I will shoot a movie tonight and post if anyone cares to see.
