Hello, was hoping for a bit of advice 
Im looking to swap my existing res for a tube res (Phobya 250 Balancer) which ive got at a good price from another forum.
when I actually then looked at it and thought about it (having never used this or any other type of tube res) I realised I dont actually know how they work
This is my setup at the moment:
As you can see I have kept the loop simple and short with out the bottom, into the CPU block out into the rad out the rad into the top of the res.
So i was looking at mounting the pump at the bottom of the res (with T Line for draining) and using a "similar" configuration, but that's when i realised that the anti cyclone (I assume) is so you can have inlet and outlet next to each other and the port at the top is for a fillport ?
If so I would (I assume) be looking at Option 1 below, whereas I would, ideally like Option 2
Is there any reason I have to go option 1 or cant go option 2 ?
Any thoughts observations and suggestions would be much appreciated

and swapped out my CPU block with an EK Supreme HF (bought from the MM):
