I am setting up a new 100 gallon tank and have decided to run my RO and media reactors thru the wall in the garage. I have started a manifold but have not finalized design. Would it be bad to run UV and gfo/carbon reactors in series or should they be independent or in parallel? They would still be feed from 1 pump via the manifold. Any pro's or con's to having the UV feed from the media reactor?
