The Ultitube has an output that can be used for fans up to 25watts, but I bet all those fans would exceed this. Personally, I would go with either a Quadro or Octo fan controller, depending on any potential future needs. AQ also sells fan splitters but I am not familiar how you would integrate that into the AQ equipment (non-Aquaero) you have.

I highly doubt non-AQ pumps will work with AQ stuff, but I will let someone else confirm this.

PWM controlled EKWB pumps can be adjusted with Aqua Computer controllers just fine. Any PWM fan controller should do, actually.
My setups are the following, installed in two separate computers:

• Octo controlling an EKWB D5 pump (and fans)
  
• Quadro controlling an EKWB DDC pump (and fans)
  

Each pump has its settings / curves in the "Fans" panel in Aquasuite. That works for me as all PWM ports on the Aqua Computer device can be named for easy identification, e.g., "Pump".

Both of these devices, Octo (8 PWM ports) and Quadro (4 PWM ports), have very similar features and capabilities. Even the Quadro can power a good number of (daisy-chained) fans: I had 3 groups of 4 fans each until I switched to Octo in that particular computer. The Octo does not provide any extra power in total (still 25 W per port, max 100 W total), but it obviously has more individually controlled ports. Nevertheless, I am only using 4 PWM ports on the Octo. In my opinion, these controllers work best when directly connected to a temperature sensor (up to 4 sensors) which can then be used as the data source for fan and pump curves.

I have no experience in using more than one Aqua Computer USB device simultaneously in a single computer.

If you are going to control the LEDs in the Phanteks D30s with Aquasuite, be aware that the LEDs are arranged in 15 groups of 2 so they are not individually addressable. If you tell Aquasuite there is 1 LED, 2 LEDs will light up. If you tell Aquasuite there are 15 LEDs, all 30 LEDs will light up. I don't know why Phanteks did this. The LED pairing reduces control granularity by 50% and RGB effects that sequentially light LEDs will look strange on a D30 fan. IIf you are using a Farbwerk360 RGBpx controller it will also throw off the LED power calculations because for each D30 fan, Aquasuite will think its driving 15 LEDs when its really driving 30 LEDs.
