Red Sea Reefer 450 manifold

[Frank Curreri]

My wife bought me a Red Sea Reefer 450 deluxe 6 months ago. After a lot of research, (new to the hobby), I’m finally ready to get started. I want to build a return manifold so I can add on equipment easily in the future. How do I join 1” pvc to the Red Sea return pipe? Any recommendations are greatly appreciated.

Welcome to R2R!!

I’m not a Red Sea guy but I’m sure we can figure this out. Can you post a picture of the plumbing in question?

It's metric sizing, not sure for your exact tank what size they use, but it actually states it on the pipe in mm. Most likely 25mm I think.
Anyway, to join to standard sized piping you have to buy metric adapters and a metric joiner (coupling, union, etc). The easiest way to do this is to go on coralvue.com and they have what you need. If shipping looks insane like it did for me, call them. Mine were shipped for like $6 and got here fast.
That said, the plumbing on my Reefer 750 is currently the bane of my existence and I wish I could just straight up replace it. Unfortunately I can't though because of the bulkheads.
