Strong enough returm pump?

[T33BLACK]

I have a 135g reef with trigger 39 sump. Looking to replace my return pump as mine is on its last leg and looking for some help. I really am leaning towards the cor-20 from Neptune so far but open to suggestions. My issue is my return line is already 3/4 hard pipe into a manifold for a uv and reactor and wondering thoughts on if I need a stronger pump being that it's only 3/4 pipe and needs to supply the manifold? I'm hoping the cor-20 would be enough as it does come with 3/4 fittings and is rated 2000gph but of course that will be cut down with the manifold obviously.

I have a 120 plus sump and a wave line dc pump. I run a manifold and 3/4 and I keep it near the lowest setting. I still have all my reactors running on valves. It’s probably pushing 500gph tops.

COR 20 good
Sicce 4.0 and 5.0 also good

Thats cool I'd be happy with that

I’ll add the Vectra M2 to the list. Flow and head similar to the Cor 20

This is going to sound weird but it’s not a recommendation for the wave line, just the gph requirements. Mine was used and works but not enough experience long term to recommend.
