That's an interesting point. Using the ProfiLux would also let you sync different kinds of pumps as well.I agree, the Maxspect controller is very good. But it is only good for a maximum of 2 pumps. If I could sync 2 controllers together with each controlling 2 pumps I would have gone that route.
2 pumps aren't providing quite enough flow so I'm putting two of them end to end on each side of my tank.
I have an issue with my tank because it has a corner overflow. So the Gyre doesn't fit across that end. I'm trying different things in terms of placement but may end up having to add one or more "regular", round, powerheads as well.
I still wish they could be directly controlled though...
