Tunze Y Adapter Cable 7090.300

I used this cable to connect two 6040DC controllable tunze pumps and a tunze moonlight without any issues. Take note, when the tank lights go out and the moon light activates, the pumps will default to whatever setting the "pulse power" knobs are set too. So in my instance I have them set at the lowest setting for less water turbulence at night. When the tank lights come back on, the two pumps will resume their daytime settings ( whatever you set them at) <br>Also note: The moonlight will not come on EVERY night, but the pumps will be in their low setting, so yes the moonlight sensor is triggering the low pump settings. Just look at the controller module lights and yiu can verify this easily. The instructions of the 6040 pump has a section describing the lunar cycle and this function in more detail, so dont freak out and assume the moonlight is malfunctioning. Hope that helps!
