Rowaphos in a reactor pump placement...help

[the.cornish.reefer]

So I have Rowaphos set up a media reactor. I have a separate pump in the sump feeding the media reactor. I have pump In the first chamber after my filter roller. Which section would you have the return pipe from the media reactor going into? The same chamber, the second (which is my refuguim) or the return chamber?

Thanks

I don’t think it matters much, but I’d personally send it to the return pump chamber bypassing the refugium so the macroalgae there has more P to help it grow and take up N.
