Best place for calcium reactor output

[sd_schoppert]

Hi everyone I was wondering if it would be best to put the output of my calcium reactor into my refugium or into the area where my skimmer is. I can see good points in each way the extra co2 may help grow chaeto and having it in the skimmer compartment could help to blow off extra co2. Any suggestions on the best place or if I should just let it go into my return section. If it helps my sump has separate flow from the refugium into the return section and separate flow from the skimmer section to the return section.
Thanks all steven

I've had mine in the refugium for a couple years with no problems. When I had it in the main part of the sump, I would notice a slight drop in PH, but I've had no change in PH since having the output from the reactor in the fuge.

Thanks for the advice.
