There are MANY caveats to that. You MUST have a WaveEngine v2, you must find the ETM RF Chipset available for sale as we cannot source them anymore ourselves, you must install that, if your MP pump has ever touched the new Mobius structure, you will have to roll back firmware, and I'm not even sure if that possible, and you do not get the cost savings that a WaveEngine could provide.
With all of that, you lose the true value of the WaveEngine. Traditionally, when you purchase a pump, you get the pump, power supply, and controller...WITH EVERY PUMP.
WaveEngine is already supplying power, its a controller...all compatible pumps are sold as a PUMP ONLY option at about half the cost, and you install it directly to the WaveEngine.
I HIGHLY recommend checking out the Reef Octopus OctoPulse pumps...they are a wide flow pump that is angular. Very high quality and low maintenance. And again...sold as a pump only that adds direct to your WaveEngine.
