It is possible to use Rowaphos and carbon in the same reactor as chemically they will not have an impact on each other. We would however not reccomend it for a couple of reasons.

1. ROWAphos will generally require a slower throughput of water compared to carbon.
2. In normal curcumstances the carbon will be exausted before the ROWAphos, if they are mixed together you will have to change them together meaning that you may be disposing of media that is still useful.
