I do have the same problem. I successfully get the d5 recognized by the aquaero xt v5 ( throught the aquasuite not by the aquaero xt itself). I can adjust speed with the slider, settings is kept in the aquasuite interface but no change at all for the pump. Flow stay the same ( i got a flow meter) pump noise is the same too. The pump is connected to an atx power suppply and to the aquaero with aquabus cable.

hi, Reading the manual i understand tht i connect my aquastream with the high aquabus connector. How am i supposed to connect the second one? Thx
