Vortech Pump

I have 2 tanks. A 75 gallon reef tank that I've had for a long time and a 93 cube that I just got. The 93 cube has a Vortech MP40 ES wireless. My question is if I get 2 MP10 wireless pumps for my 75 gallon, can I integrate them with the existing wireless system?

Second question: Will 2 MP10's be sufficient for a 75 gallon? Too much?



Thanks!
