The D5s are stronger and quieter than those other pumps you posted. The D5s connect to the Aquaero 6 via aquabus connection, that way it is monitored and controlled.

Why are you looking to get two D5s? Is it a very high end complex loop or your typical loop? Looking for redundancy?

Having done more research - I am looking for the quiet operation. I think dual D5 set-up will give better result. Looking to use #mce_temp_url# with two #mce_temp_url#

How do I connect to the Aquaaero 6 XT?

The aquacomputer D5 USB/aquabus pumps may be connected to the motherboard via USB and will show up in aquasuite under their own tabs.

The pumps may also be connected to the aquabus high port on the aquaero using an aquabus splitter..
if connecting the pumps by aquabus, you will need to change the aquabus address for one using the USB connection first.
-aquabus has 4 MPS addresses (12, 13, 14, 15) available and must be unique for each device.
-the D5 USB.aquabus pumps come from the factory set to 12, so one would need to be changed.
In order to monitor and/or control the pumps with the aquaero, you will need the aquabus connection.
Both USB & aquabus connections can be used simultaneously, or independently.

The aquabus can be a 3 or 4 wire bus, with the 4th wire providing dc power.
-The 4th wire is not needed for all MPS devices, but it doesn't hurt anything if connected as it is ignored if not needed.
-So until you feel comfortable knowing exactly when a 3 or 4 wire aquabus cable is needed, always use the 4 wire aquabus.
