Yes, luckily my girlfriend likes the tanks as much as I do. For Christmas she bought me the Tunze 7095 multicontroller and a pair of 6055's. I love the way you can make all kinds of wave patterns and adjust the flow of the powerheads.
They may be overkill on the 90 for now, (most of them are at 60%) but I'm sure within a couple of years we will be upgrading to a larger tank anyway so thy can make the move as well.
