I currently have a 3 stage chloramine/chlorine filter unit that I use on a freshwater tank. I will be changing over to saltwater soon and not sure if some of the extra filters i have can be used once I add an ro membrane and di resin.

Currently it goes 5 Micron Sediment > 5 MICRON MATRIKX CTO CARBON BLOCK >0.6 MICRON MATRIKX CTO PLUS CARBON BLOCK.

I have unused of each of these, do the filters named make decent replacement in an ro/di unit?

Also, What is the flow order typically for a 5 stage ro/di unit from tap to output?

Should work just fine. I think Bulk Reef Supply sells those same carbon blocks. If the five stage ro/di has dual carbon, it would go sediment, both carbon, RO, and then the DI after that. Other five stages might have single carbon, but dual DI at the end.

I built the unit from individual parts from BrS. I just wasn't sure if they were adequate for what I want to achieve.

Yep.. slap on a RO membrane and a DI stage and you are good to go
