It is not possible to connect both to the Aquaero, the LEAKSHIELD requires a USB connection.
The D5 NEXT can be connected to the Aquaero via Aquabus, but then it cannot be completely addressed via the Aquasuite.
I would recommend a USB hub, such as the Hubby 7, then you only need one USB cable to the computer and still all devices are fully usable.
what do you mean by it would not be completely addressed via the aquasuite ???
(i want to replace my aquastream XT with this one and i have an aquaero 5 pro)
what are the limitations (except that you cannot use it's port for rgbpx control) ?
thanks
