i only have one pump hooked up ,i found out that the cable or y that i bought doesn't seem to be working so i need to find out how i can order these parts from u guys.i bought a 4 pin y ,now i had my one pump 3 pin aquabus/flow hooked to the y 4pin then on the other end of the 4 pin i had my flow meter or sensor hooked to the aquabus 4pin then had the 4 pin y hooked to the aquaero5 xt aquabus high flow 2. it would only read one and that one was the flow sensor or meter.so i guess i have to order this form u guys so they will both show up on the aquaero 5 xt. i plugged them in one at a time and they both worked so it wasn't the pump or flow sensor. thank god..lol oohhh please tell me the cable connectors that i will need to connect my one aquastream xt aquabus and my flow sensor aquabus to my aquaero5 xt high flow 2 aquabus..and how much will this cost in usa money..lol ohh thanks again shoggy.ps and what fan connectors do u recommand for me to hook 11 fans to the aquaero 5 xt or is this to much for it. i also need the suction side for my pump thats why i dont have my 2 pumps hooked up,i crack it.opppsss this is why i only have one now but dont hink i need 2 until i cool my 2 680 .thanks again
