Yea the refugium is the first chamber of my sump that then goes through 2 baffles and there is another section with more filtrations then the final chamber where th return pump is.
so if anything is to make its way to the tank from the fuge its got a fair journey to go before it gets there.
yeah that may be a tuff journey considering the fact pods are relatively small...im not sure and dont wanna give you a answer on if they are making it cuz if they are going through filters may be a tuff journey. Maybe ski will come along and answer that one for ya.
