hi all, for the Red Sea reefer 350 it recommends 4,000 LPH but I was wondering is it better to run two 2,000 LPH or one 5,000/ 4,000 LPH?

Personally I'd run one and make sure it's oversized and adjustable. Then have a back up on a shelf somewhere incase there's ever an issue. Doesn't have to be too big, just better to not have to run full speed.
