The IceCap Gyre Dual Pump Controllers do not work with Maxspect Gyres. You might take a look at the HYDROS WaveEngine if you're looking to use more than two pumps in your system. It works with Maxspect along with a variety of other brands.

I work on our marketing team and occasionally (but not intentionally) take breaks from the forum to finish big projects... like the redesign of our website, which just launched last week.
