Probably the RD3 150. That or the 230 depending on what else you would want to run from the return pump. I.E. Reactors, chiller loops etc. Head pressure would also be a factor when deciding.

In that case, the RD3 150 would provide more than enough flow and you'd never need to run it at full power.
