So I have a red sea reefer 750 and decided I want to run carbon in a reactor and build a manifold. I found one online I like and purchased parts that were listed for that manifold. One thing, I have no clue how to do any of this. I have never plumbed a reef tank before, so this varios 8 return pump with no instruction manual is throwing me for a loop. I am in way over my head. I don't know what parts go where and I honestly didn't realize how difficult this is. Not sure anyone can help, just lost. If it wasn't for this whole plumbing thing I might have a chance at this hobby.
