How many pumps can a Aquaero have hooked up to it at one time? Does the Aquabus provide power to the pumps or do you still need to hook up the power via molex cable? In what situation would one need to buy a poweradjust 3 or ultra?
You can connect up to 4 mps devices
(flow, pressure, d5 pump) to Aquaero via aquabus at the same time. Aquabus doesn't provide power for pump operation, only for controller electronics and you have to
hook up the power via molex cable.
Poweradjust is needed if you want to use a pump without PWM or Aquabus with Aquaero and control it via currency.
