Iwaki RD30...for those that have experience with one, I have a few questions please

[Mutant_Tractor]

Im not in a position to change pumps now, i spent £120 on this pump and theres no returning it now,
Well if they sell it with the RD-30 it must run it, ill see if i can get one here in the UK, its a pain ordering stuff from the US

EDIT:
While im at it, im deciding on a res, i have 1/2' ID tubing (Tygon) and i want to know whats the least restrictive res, i really want a tube one like the EK Res the V2 one but aparrently is a 1/4' bore in it but i guess with my pump i should have a for of restriction to make it run smoother?

EDIT #2:
Did more research and went for the EK Res, i dont really need to worry about flow rates with this pump, now just gotta figure out where to mount the damn thing and what PSU to use, if i can find that one in the UK ill buy it,
