Hi all. New Reefer over here. I am planning to purchase a Red Sea 425 xl and want to run two return pumps for redundancy. One pump will go directly to return pipe. Other pump will power a UV sterilizer and then t into the return pipe. A few questions-do I have to have the same pump times two for things to work or can I mix and match? Secondly, if the recommend flow is 1,000 gph, should I shoot for each pump that can produce 500 gph or get pumps that produce 1,000 each and then scale them back with either a controller or gate valve? Lastly, what are some recommendations for pumps for what I am intending to do? Thanks everyone!
