You will have to buy metric to standard conversion couplers. I used 32mm to 1” couplers from BRS. Once you have that it’s pretty straight forward on plumbing it to your specific sump and however you plan to place it in your stand.I see you changed the drain system. May I ask how you ran the returns ? I am in the process of setting up a 70.2 I went with a fiji 20 sump.
